# Suppose we wanted to see what effect a different operational

Suppose we wanted to see what effect a different operationaldefinition for relaxation during studying would have. Instead of using a dimlylit room, the scent of lavender, and soft music, suppose we had students selecttheir own light level, scent, and music in which to study, encouraging them tohelp whatever would help them to relax. We then measured the number of errors,each student in this condition made on a recall of material learned under theseconditions, and obtained the following errors for 50 students: 5, 2, 2, 1, 0,4, 2, 1, 1, 0, 3, 3, 0, 0, 0, 1, 0, 2, 1, 7, 5, 0, 2, 4, 0, 5, 3, 6, 0, 1, 3,5, 3, 6, 0, 1, 3, 5, 2, 4, 2, 0, 5, 1, 3, 6, 4, 1, 0, 3, 4, 2, 0, 1, 3, 61) place the data in an array2) Group the data and place the results in both a table anda histogram and discuss the results (shape of the distribution. Etc.)3) calculate the mean, median, mode, and standard deviation4) discuss your results in #3 (describe the distribution,choose the best measure of central tendency, etc.)
