Document Summary

Pre-lab 2: chapter 4: make up a set of data for which the mean is greater than the median. (4. 4) Median: 6: a group of 20 rats running a straight alley maze required the following number of trials to perform a predetermined criterion. Calculate the mean, median and mode number of trials to criterion for this group. (modified from 4. 7) Mode: 19 and 21: create a sample of ten numbers that has a mean of 8. 6. How did you accomplish this? (the answer will help you later to understand the concept of degrees of freedom. ) (4. 10) 86 = x therefore the ten numbers could be: 1+2+3+4+5+6+7+8+9+41 = 86: why is the mode (but not the mean and median) an acceptable measure for nominal data? (4. 15)
