To Calculate: Quartile 1 and Quartile 3 for the given set of values.
The Quartile 1 and Quartile 3 of the given data set are 42 and 69 respectively.
Given:
The data set is shown below
Concept:
Quartile 1 of a data set divides the lower 25% of the data and the upper 75% of the data in a data distribution or it is the median of the first half of the data distribution. Quartile 3 of a data set divides the upper 25% of the data and lower 75% of the data in a data distribution or it is the median of the second half of the data distribution.
Calculation:
Given data set has a total of 10 data values. Considering the first half of the data set, the first five data points as shown below
there are a total of five data values and the middle value of the first half of the data distribution is the third value in the above data distribution “42”. Thus
Considering the second half of the data set, the first five data points as shown below
there are a total of five data values and the middle value of the second half of the data distribution is the third value in the above data distribution “69”. Thus
