Document Summary
To compare one sample or population to another population or sample to see if they are different or the same. We need to be able to calculate the mean of the sample. If there is a difference in the means. We must decide if it is due to chance or due to a real difference in the samples. Would be weird if it was the exact same every time. We need some way to define chance as a number. We need to determine how accurately our sample reflects the population it is from. Start with looking at one score and see how to determine where it is relative to other scores in the population. (chapter 5) Introduce the concept of the normal distribution. (chapter 5) Use a table that allows you to convert your scores into a probability (as long as it came from a normal distribution) back of book.
