Are q2, d5, and p50 equal?
Answers
Answer:
5th decile and 50th percentile are same
Given : q2, d5, and p50
To Find : are all these equal
Solution:
q representing quartile ( data divided in 4 equal part )
d representing decile ( Data divided in 10 equal parts)
p = percentile ( data divided in percentage )
q1 = lower Quartile = p25 ( 1/4 of data )
q2 = Median = p50 = (1/2 of Data) = 5 deciles
q3 = upper quartile = p75 ( 3/4 of Data)
d5 = p50 = q2
Yes , d5 = p50 = q2 are equal
The lower quartile Q₁ , or the first quartile, is the median of the lower half of the data in a set.
The upper quartile Q₃, or the third quartile, is the median of the upper half of the data in a set.
Median is the middle element or the mean of two middle elements in a numerical data set with the elements ordered by their value. or also called Q₂ ( 2nd Quartile )
