a. She found the difference of the least and the greatest values.
b. She added all the values and divided the sum by 5.
c. She found the mean and then found the average deviation of the weights from the mean.
d. She found the difference of the upper quartile and the lower quartile.
e. She found the value that appeared the most often.
f. She found the middle value after arranging all the values from least to greatest.
Option:
a. Range
b. mean
c. Mean absolute deviation
d. Interquartile range
e. Mode
f. Median

Answer 1

The measures of center and measures of variation for the given data can be matched as follows: Range, Mean, Mean absolute deviation, Interquartile range, Mode, Median.

Step-by-step explanation:

The measures of center and measures of variation for the given data can be matched as follows:

a. She found the difference of the least and the greatest values - Range

b. She added all the values and divided the sum by 5 - Mean

c. She found the mean and then found the average deviation of the weights from the mean - Mean absolute deviation

d. She found the difference of the upper quartile and the lower quartile - Interquartile range

e. She found the value that appeared the most often - Mode

f. She found the middle value after arranging all the values from least to greatest - Median
