... did very poorly or very well on the test…but the mean was the same as period 3! The mean is not a good measurement of the performance of the students in Period 6 because most students didn’t get a C. • We use standard deviation to figure out if the mean is representing an accurate view of what is go ...

... difference by manipulating your independent variable. A p-value of .05 means that you will be wrong approximately 5% of the time if you reject the null hypothesis. In most psychology experiments, we require a p-value less than .05 to conclude that a significant difference exists between the samples ...
