Explanation / Answer

Q1 is the inter quartile or 25th percentile value.

To find this value we have to arrange the data in the ascending ( smallest to largest) order and then we have to find the (n/4)th observation.

Where n is the total number of observations.

As per the given data

the total number of observations are n = 25. and the Q1 is (25/4)th observation i.e., 6.25th observation.

since there is no such observation we take the mean of 6th and 7th observation.

therefore Q1 = (69+70)/2 = 69.5.
