#### QUESTION

Solve the following:

1) Find out Q3 from the given data.

2) Draw a population growth curve from the given data.

 Year Population (in Crores) 1951 36.1 1961 43.9 1971 54.8 1981 68.3 1991 84.6 2001 102.7 2011 121.02
Sum

#### SOLUTION

 Year Population (in Crores) Cumulative frequency(cf) 1951 36.1 36.1 1961 43.9 80 1971 54.8 134.8 1981 68.3 203.1 1991 84.6 287.7 2001 102.7 390.4 2011 121.02 511.42 N=511.42

Q3 = size of 3${\left(\frac{n+1}{4}\right)}^{\text{th observation}}$

Q3 = size of 3${\left(\frac{511.42+1}{4}\right)}^{\text{th observation}}$

Q3 = size of 3${\left(\frac{512.42}{4}\right)}^{\text{th observation}}$

Q3 = size of 3 (128.105)th observation

Q3 = size of 384.315th observation

Size of 384.315th observation lies in cf 390.4

Hence quartile value in the year 2001.

Q3 = year 2001.
