The following table gives the numbers of branches and number plants in a garden of a school.

Calculate the mean, median and mode of the above data.

We have

For Mean:

Mean is given by

⇒ [from the table]

⇒ Mean = 4.05

For Median:

Total number of items, n = 5 (odd number).

When n is odd, median is given by

⇒

⇒

⇒ Median = 3^rd term

Count 3^rd term from the arranged numbers in the table.

The 3^rd term = 4

⇒ Median = 4 [∵ Median = 3^rd term]

For Mode:

Mode is nothing but a number with highest frequency. Interpret the column ‘No. of plants’ in the terms of frequency.

Here, highest frequency is 28. Then, corresponding no. of branches are 4.

⇒ Mode = 4

Thus, mean is 4.05, median is 4 and mode is 4.
