1) Write the formula of Q1 and Q3.

2) Find out the median of the above data?

3) Find out the cumulative frequency of the last value in the above data.

4) Find out the value of 'n' in the above data

1. Formula of Q1

Q= Size of 1${\left(\frac{n+1}{4}\right)}^{\text{th}}\text{observation}$

Formula of Q3

Q= Size of 3${\left(\frac{n+1}{4}\right)}^{\text{th}}\text{observation}$

2. Median = Q2

Median = Q2 = Size of 2${\left(\frac{n+1}{4}\right)}^{\text{th}}\text{observation}$

= Size of 2${\left(\frac{38+1}{4}\right)}^{\text{th}}\text{observation}$

= Size of 2${\left(\frac{39}{4}\right)}^{\text{th}}\text{observation}$

= Size of 2 (9.75)th observation

= Size of 19.5th observation

= Size of 19.5th observation lies in cf 24

Hence, quartile value = 30 marks.

3. The cumulative frequency of the last value in the above data is 38.

4. The value of 'n' in the above data is 38.
