What is the interquartile range of the data set? enter the answer in the box. key: 1|5 means 15

The interquartile range(IQR) of the data set is:

                               10

The data points according to the stem and leaf plot are as follows:

           28    40    43    43    45   50    50

We know that the median of the data is the central tendency of the data and always lie in the middle of the data.

Here looking at the data we have:

Median= 43

Similarly the lower set of data is:

                    28    40    43

Hence, the first quartile or the lower quartile i.e. is the median of the lower set of data.

Hence,

Similarly, the upper set of data is:

                 45   50   50

Hence, the upper quartile or the third quartile i.e. is the median of the upper set of data.

Hence,

The interquartile range(IQR) is calculated as:
