29:05 Concluding Remarks
Learning
Outcomes:-
Through this module, you will gain understanding on:-
1. Quartile
2. Deciles
3. Percentiles
And their estimation
(All formulae at a glance)
Partition Value = Value that divides the series into more than two parts
1. Quartile
2. Deciles
3. Percentiles
QUARTILE = End value of each part when a statistical series is divided into 4 equal parts
It is written as Q
1. First quartile or Q1 = lower quartile, has 25% of the items of the distribution below it and 75% of the items above it
2. Second quartile or Q2 = same as Median, has 50% of the items below it and 50% of the items above it
3. Third quartile or Q3 = upper quartile, has 75% of the items below it and 25% of the items above it.
Estimation of Q1 and Q3 -
Data is first arranged in ascending order (preferably)
DECILES -
Distribute the series into 10 equal parts
Expressed as D
We have nine deciles from D1 to D9
PERCENTILES -
Divide the series into 100 equal parts
Expressed as P
There are 99 percentiles in a series ranging from P1 to P99
P50 = median value, centrally located
P25 = Q1
P75 = Q3
If a student has secured 89 percentile in an MBA entrance examination, it means that his position is below 11 per cent of total candidates appeared in the examination.
