Question

I need help ASAP!!
Which of the following are appropriate measures of central tendency to apply to the list below of heights recorded in the high-jump event at a track meet?

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
