Q1: Below are some of the descriptive statistics for a specific dataset. N=50; mean=10; median=5; range=15; standard deviation=10; interquartile range=5; skewness=3.5 (i.e. right skewed).

Which of the following do you think it is more appropriate to be used to describe the location of the data?

Based on Q1, which of the following will you use to describe the variation of the data (i.e. measure of spread)?

Based on Q1, which of the following do you think it provides sufficient information about the data?

Solution

The three most common measures of location are the mean, the median, and the mode.

Measures of variability: the range, inter-quartile range and standard deviation.

By this we can say that...

a) mean describe the location of the data.

b)interquartile range describe the variation of the data.

c) n, median and standard deviation provides sufficient information about the data.
