<h3>what is measure centre and measure of variation? </h3>
A measure of central tendency (measure of centre) is a value that attempts to describe a set of data by identifying the central position of the data set.
The measure of central tendency includes the mean, median and mode.
The measure of variation describes the amount of variability or spread in a set of data.
The common measures of variability are the range, the interquartile range (IQR), variance, and standard deviation.
Therefore, the measure of centre includes mean median and mode and the measure of variability includes range, interquartile range and mean absolute deviation.

Answer:
40/21
Step-by-step explanation:
-4/7+(-4/3)
common factor is 21
=21/7×-4-21/3×4
=3×-4-7×4 all divided by 21
=-12-28 all divided by 21
=40/21
