Question 1
|
The values which divide the frequency into four equal parts are called:
|
Coefficient of variance
|
|
|
Range
|
|
|
Dispersion
|
|
|
Quartiles
|
Question 1 Explanation:
The values of a variable that divide a distribution into four equal parts are called quartiles. Since three values are needed to divide a distribution into four parts, there are three quartiles, viz. Q1, Q2 and Q3, known as the first, second and the third quartile respectively. For a discrete distribution, the first quartile (Q1) is defined as that value of the variate such that at least 25% of the observations are less than or equal to it and at least 75% of the observations are greater than or equal to it.
