Answer #1

I have collected a Voluntary sample.

Since I've posted flyers around campus asking the people who are interested to contact me to take part in the experiment, only those interested in the experiment would contact me. The sample here is chosen by the viewers or the people who have seen the flyer themselves and not by me. It's a type of non probability sampling. The people who are interested in the topic only take part in the survey and it can lead to some sort of bias in the results as this is not a random sample and can lead to voluntary bias.

If I told you that we know that 35% of all students actually...

PART 1: Sampling How we select our sample will directly influence the external validity of the study. If a sample is representative, then our external validity is stronger.

You are interested in looking at the relationship between student-to-teacher ratio and GPA at California 2- and 4-year colleges. You suspect that average GPA is higher at 2-year colleges where student-to-teacher ratio is low, relative to 4-year colleges colleges...

Imagine that you have set up a Kirby Bauer experiment on Mueller Hinton agar (non-selective agar) in order to test if Escherichia coli is susceptible or resistant to Drug X. After 24 hours, you notice a zone of inhibition (clear zone) around your antibiotic disc and determine that E. coli is susceptible to Drug X. You then take a cotton swab and subculture a sample from this zone of inhibition (where no growth was apparent) onto a new agar plate...

You have just received $100,000 from me as a grant for an experiment. I want you to create a stock portfolio worth $100,000, i.e. 'buy' stocks worth $100,000. This is how you can 'buy' a stock in this experiment. Suppose you want to buy 100 stocks of Apple. Look up its symbol (Appl), and its closing price (Suppose that on Friday, Feb. 22, was 172.99). Now multiply 100 by $172.99. You just spent $17299.00 on this stock. Pick another stock...
