Explanation / Answer
Calculator Directions for Statistics and Graph
Finding the mean, median, and mode on the calculator:
Stat, Edit, Enter each student’s total into List 1
Stat, Sort A, L1, to put scores in order, lowest to highest
Stat, Calc, 1-Var Stats
X is the mean; below is the median; observe the list to see the
Mode
Finding standard deviation on the calculator:
Stat, Calc, 1-Var Stat
sx is Standard deviation
Constructing the histogram on the calculator:
Put scores into grouped categories, e.g. 0-5, 6-10, etc.
Tally student data
In list 1, put maximum value of each group, e.g. 5, 10, etc.
Enter tally into list 2
For window: Xmin 0
Xmax 40 (or whatever is max of groups)
Xscl 5
Ymin 0
Ymax 8 (or whatever is highest tally)
Yscl 1
2nd Stat Plot, 1, On, Type: histogram, L1, L2, Graph
Trace to see frequencies
Study has a greater spread relative to its mean.
