Question

13. Find each measure listed below. Round all answers to the nearest tenth. (7 points)
10, 11, 4, 7, 12, 11, 16, 6, 9, 15
a. Mean: ___________ d. First Quartile: ___________
b. Median: ___________ e. Third Quartile: ___________
c. Mode: ___________ f. Standard Deviation: ___________
g. Variance: ___________

Answer 1

The mode is the repeated value of 11.
The others will require4 calculation.

Answer 2

4,6,7,9,10,11,11,12,15,16

mean = (4 + 6 + 9 + 11(2) + 12 + 15 + 16)/10 = 84/10 = 8.4
median (middle number ) aka Q2 = (10 + 11)/2 = 21/2 = 10.5
mode = 11

Q1 (first quartile) = (6 + 7)/2 = 13/2 = 6.5
Q3 (third quartile) = (12 + 15)/2 = 27/2 = 13.5

as for variance ans standard deviation...
