Question

The pair of averages whose value can be determined graphically?(a) Mean and Median(b) Mode and Mean(c) Mode and Median(d) None of these

Answer 1

The value of mean and median of a table can only be found graphically, so the answer is (a).

Answer 2

The correct answer is option (c) Mode and Median.

Mean cannot be found out from the graph directly. For example - If the mean value of 45, 89, and 56 are to found out, you need to calculate it manually and answer cannot be found out by looking at the graph plot of 45, 89 and 56.

Median value of the data can be calculated graphically by plotting the data on less than and more than ogive.

Mode value is found out graphically by representing the data in a histogram and marking the heights of the histogram using class intervals. The highest rectangle corresponds to the modal class of the series.
