Gardening is one of my favorite pastimes.
It’s cheapskate approved and a fine american tradition. It’s also a terrific way to get a
little exercise, enjoy the great outdoors and best of all save some money, by growing your own grub. Stay Cheap! Hey! I’m Jeff Yeager the ultimate cheapskate and host of the Cheap Life. I’ve got some great cheapskate secrets that will help you
get the most out of your garden. Real estate experts say that landscaping,
when done right, can increase the value of some home homes by tens of thousands of dollars and they say money
doesn’t grow on trees. LJ: Speaking of money leave your best cheapskate gardening tips in the comment section below for a chance to win a fifty dollar gift card. First try going flowers, vegetables and herbs from seeds rather than buying seedlings. Plants that start from seeds like these will cost about ninety five
percent less. And that’s no small potato. You can start seedlings in a wide
variety of repurposed containers like cardboard boxes, old toilet paper tubes, even newspaper, or half an egg shell an avocado shell and whatever you do don’t know that away! Plastic clam shell containers are great for making a miniature greenhouse. The perfect incubator for your seedlings. Growing your own food is one of the best ways to
cut down on your grocery bill, take herbs for example. A pack of store bought herbs can cost up to six bucks and only last a meal or two. But if you grow your own it’ll only cost
a couple of bucks and some TLC and you’ll have beautiful, delicious herbs throughout the year. And did you know that newspapers make terrific weedwhackers? Putting down several layers of newspaper before you mulch will help retain moisture and further prevent those pesky little fellers from popping up. Check with your local landfill and road crews for cheap and sometimes even free mulch. Cheapskate shoutout! Here’s a great tip from the daily grain
dot com. Sprinkle good old-fashioned rock salt on gravel driveways and
pathways; places where you definitely don’t want anything to grow in the spring time. It’ll keep weeds from taking root all season long. You know I like to stock up on discounted rock salt at the end of winter. And if there’s any left, its margarita time! Gardeners know the importance of PH
balance in healthy soil. Here’s a cheap and easy home soil test you can do
with just a few household items. Scoop some soil into an container and then add a half a cup of vinegar. If the soil bubbles or fizzes, its alkaline. If there’s no reaction at all scoop some fresh soil into another container and mix with a half a cup of water. Then add a half a cup of baking soda and
see if that soil bubbles and fizzes. If it does that means it’s highly
acidic and you should sprinkle wood ash, lime, coffee grounds or even eggshells on your dirt to help boost the PH level. For a soil that tests alkaline, try spreading pine needles, or sulfur around your yard. This will not only amend the health of your soil, it’ll make your darling flowers say Flower: ” Thank you Mr. Cheapskate” Jeff: Awww Your welcome little fella. I’m Jeff Yeager for the Cheap Life.

One of the most important concepts in statistics is the meaning of the P-value. Whenever we use Excel or other computer packages to analyse data, one of the key outputs is the p-value or sig. In formal terms, The p-value is the probability that, IF the null hypothesis were true, sampling variation would produce an estimate that is further away from the hypothesised value than our data estimate. In less formal terms, The p-value tells us how likely it is to get a result like this if the Null Hypothesis is true. We will now go through this step-by-step with an example. Helen sells Choconutties. Recently she has received complaints that the choconutties have fewer peanuts in them. than they are supposed to. The packet says that each 200g
packet of choconutties contains 70g of peanuts or more. Helen can’t open up all the packets to
check as then she wouldn’t be able to sell any. So she decides to use a statistical test on a sample of the packets. The null hypothesis, often called H “nought” is the thing
we’re trying to provide evidence against. For Helen, the null hypothesis is that the
choconutties are as they should be. The mean or
average weight of peanuts in the packet is 70 grams. The alternative hypothesis called H1 or HA is what we’re trying to prove. The customers had complained that the weight of peanuts is less than what it should be. So the alternative hypothesis is that
the average rate of peanuts is less than 70 grams. Helen decides to use a significance
level of 0.05 if the P-value is lower than this, she will reject the null hypothesis Having decided on her hypotheses and on the significance level Helen takes
a random sample of 20 packets of Choco-nutties from her current
stock of 400 packets. she melts down the Choco-nutties and weighs the peanuts from each packet. If all of the values were lower than 70
grams with a mean of 30 grams for instance,
it will be quite obvious that the bars did not have the required number of
peanuts. It is very unlikely that you’ll get 20
packets with a mean of 30 grams if the overall mean of all the packets in the
population is 70 grams Conversely, if all the values of the 20
packets were much higher than 70 grams, it would be obvious that there were
enough peanuts and that there was nothing to complain about. However, in this case the 20 packets
contain the following weights of peanuts and the mean is 68.7 grams. This caused Helen to ask herself: “Does this provide enough evidence that the bars are short of peanuts or could this result just be from luck?” She
asks her brother to use Excel to find the p-value for this data, comparing with the mean of 70 grams. The P value is 0.18 Judging from the data that we have,
there is an 18 percent chance of getting a mean as low as this or lower if there is nothing wrong with
the bars. That is, if the null hypothesis is true and the mean weight of nuts is 70 grams or more. This P value of 0.18 does
not provide enough evidence to reject the null hypothesis. In this case helen does not have
evidence to say that the bars are short of peanuts. This is a relief! The smaller the
p-value is, the less likely it is that the result we got was simply a result
of luck. If the P value had turned out to be very
small we then would say that the result was
significantly different from 70 grams. In general we start by saying that the
null hypothesis is true. We take a sample and get a statistic. We
work out how likely it is to get a statistic like this, if the null hypothesis is true. This is
the p-value. If the P value is really really small, then
our original idea must have been wrong, so we reject the null hypothesis. P is
low, Null must go. A small P value indicates a significant
result. the smaller the p-value is the more
evidence we have that the null hypothesis is probably wrong. If the P-value is large, then our original
idea is probably correct. we do not reject the null hypothesis.
This is called a nonsignificant result. The P-value tells us whether we have
evidence from the sample that there is an effect in the population. a P-value less than 0.05 means that
we have evidence of an effect. A P-value of more than 0.05 means that there is no evidence of an
effect. Sometimes a significance level different from 0.05 is used, but 0.05 is the most common one. This video uses plain language to get
difficult ideas across. Some terminology might be viewed as
incorrect by a rigorous statistician.
Good morning Hank, it’s Tuesday. Today I’d like to deliver an open letter to students returning to school. Dear students returning to school: Not to speed your re-entry into formal education with a pop quiz or anything, but in what year do you think primary education became mandatory for all American children? 1918. Germany had primary compulsory education from the late 18th century, in Japan, thanks to the Meiji reforms, by 1900, 90% of Japanese kids were in school. in England, it happen around 1880, but regardless of where you live, primary education became a requirement sometime after 1775. That probably seems like a long time ago to you, but if you look at like human history since the Agricultural revolution the entire period of time that has featured compulsory education anywhere in the world looks like… this You’ll also note this two hundred and fifty year period has been a pretty good run for humans featuring, you know, steam engines, the internet, antibiotics, skyscrapers, a stunning increase in life expectancy, home pizza delivery, water purification plants, and landing a freaking Mini Cooper on Mars. Needless to say this is not a coincidence. Take for example, Adam Steltzner, the lead engineer on the Curiosity Rover’s descent and landing team. He went to a publicly funded high school before getting in both his Bachelor’s degree and his Doctorate from publicly subsidized universities. So let me ask you a question, students about to return to school. How fraking psyched are you for the end of summer? How psyched are to have the opportunity to learn about the Universe and its inhabitants for several hours a day at no cost to you? The answer of course, is that if you’re anything like I was, you’re not psyched at all. I mean, a) you might be a bit of a social outcast.
I know I was. I never really learned how to shave, and that-that’s fine now, but back then, when I had like the Sony My First Mustache,
it was just a disaster. And b) you may often feel like
your studies are mind-numbing, instead of mind-stimulating. Like who wants to read the Taming of the Shrew? You basically have to translate it from Shakespeare into English, which is ridiculous because there is already an excellent filmic translation available in the form of Ten Things I Hate About You. So if you’re anything like me, you’re gonna spend a lot of time whining that 1) none of this will ever be useful in your real life And 2) your teachers are stupid. And 3) math is really hard and you’ll never understand it, ditto physics, history is boring, French is just an endless series of je ne sais pas literature is an impossible hunt for symbols, and physical education is an oxymoron. Well here’s the thing. When you watch the Curiosity Rover land, it is far more moving and exciting if you understand the physics, and the math, and the history behind that moment. French is useful because the French do speak English, but they pretend not to. And it’s not only literature that’s symbolic, all communication among people is symbolic. As is consciousness itself. And physical education is not an oxymoron, because your body is not born knowing how to do this! But yes, your teachers may be stupid. So are you! So am I! So is everyone. (except Neil deGrasse Tyson) The whole pleasure of being a human is in being stupid, but learning to be less stupid together! But more important than all of that, you need to remember that school is not about you! School doesn’t exist for your benefit, or for the benefit of your parents. Schools exist for the benefit of me. The reason I pay taxes for schools, even though I don’t have a kid in school, is that I am better off in a well-educated world. Public education isn’t a charity project, I pay for your schools because
I want you to grow up and make my life better. I want you to to make me beautiful books that will bring me pleasure and consolation, I want you to make me cooler cars for me to drive, and drugs so that I can live a longer, healthier life. I’m paying for your education in the hopes that you’ll invent a microwave pizza with actually crispy crust, And that you’ll spread the availability of the internet So that I can get more YouTube views in Zambia. You education isn’t just about you, your nation is making an investment in you because they believe that you are worth it. So the next time you’re like half-asleep in class, fantasizing about being a kid chosen for a special mission, or wizard school or whatever, please remember something: You are special! And you’ve been chosen for a special mission that was denied to 99.9% of all humans ever. We need you! We believe in you! And we’re counting on you. Best wishes, John Green. Hank, quick postscript for people nerdy enough to be interested in education outside of class, Please check out CrashCourse and SciShow, our educational initiatives, link in the doobly-doo. And for those of you nerdy enough to dream about being a Time-Nanny for an Evil Baby Orphanage, I have great news! A professional gaming company is Kickstarting an Evil Baby Orphanage card game. It looks really cool, so check that out as well, link in the doobly-doo. Hank, congratulations on Curiosity not crashing into Mars, I know that’s like the highlight of your year, I will see you on Fri-
