Check all that apply.

4' 9", 5' 3", 5' 4", 5' 7'', 5' 3", 5' 9", 6' 0", 5' 4", 6' 0", 6' 1", 5' 7", 5' 5", 4' 5"

A. Mode
B. Median
C. Mean
D. Range
E. Standard deviation

Answer 1

Best Answer: A. Mode
B. Median
C. Mean

the other two are not measures of central tendency.
Data:
4+9/12, 5+3/12, 5+4/12,5+7/12,5+3/12, 5+9/12,6+0/12, 5+4/12,6+0/12, 6+1/12,5+7/12, 5+5/12, 4+5/12

4.4167, 4.75, 5.25{2}, 5.3333{2}, 5.4167, 5.5833{2}, 5.75, 6{2}, 6.0833

n= 13; Σx= 70.75; Σx²= 387.8403; Σx³= 2140.408; Σx^4= 11886.2257
σ= 0.4638; σn-1= 0.4828; Variance=σ²= 0.2152; (σn-1)²= 0.2331
Mean(μ)= 5.4423; range= 1.6667; mid-range= 5.25; median= 5.4167; No Mode Probably right skewed.
Five number summary: Q0= 4.4167, Q1= 5.25, Q2= 5.4167, Q3= 5.875, Q4= 6.0833, IQR= 4.875
