Using a sample of data from a dataset, the ages of 11 respondents, calculate the measures of center and the measures of spread.
40, 42, 45, 46, 53, 54, 22, 57, 63, 22, 25
ANSWER:
The mode is 22, the mean is 42.6, the median is 45, the range is 41, and the IQR is 29
Correct! The mode is the number that occurs most often, the mean is the average, the median is the number in the middle, the range is the spread between the high and low numbers, and the IQR is the difference between the first and third quartiles. You are getting to be an expert in the measures of center and spread! Excellent work!
