Question

The following frequency distribution contains the educational levels attained by the 49 office personnel of a small company: Given the level at which education level was measured, calculate the appropriate measures of central tendency for describing the distribution given. A school district tallied the number of students in each of its nine elementary schools. The schools enrolled the following number of students: 586 892 452 525 197 484 723 509 448 a. Calculate the appropriate measures of central tendency for describing the distribution given. b. What is the most appropriate measure of central tendency to use here? Why?

Explanation / Answer

3:

Here data is categorical. So mode will be most apprpriate measure of cenral tendancy.

Mode is the data vaue with hihgest ferquency. That is mode is "Completed high school".

4:

Following is the ordered data set:

197, 448, 452, 484, 509, 525, 586, 723, 892

(a)

Distribution is not symmetric. It is skwed to left. So median will be appropriate measure of central tendancy.

There are 9 data values so median will be 5th data value. That is median is 509.

b)

Distribution is not symmetric. It is skwed to left. So median will be appropriate measure of central tendancy.
