Q2 = D5 = Median
Then what is D4 going to be?
I am talking about Deciles here..
Deciles divide a set of data into 10 equal parts. The first decile (D1) represents the 10th percentile, the second decile (D2) represents the 20th percentile, and so on. The 5th decile (D5) represents the median, which is the value that separates the data into two equal halves.
Since D5 is the median, it means that 50% of the data falls below D5 and the other 50% falls above it. Therefore, if D5 = Median, we can conclude that 50% of the data falls below D5.
Now, if we consider the data from D1 to D4, it represents the first 40% of the data (D1 + D2 + D3 + D4 = 10 + 20 + 30 + 40 = 100). Since D5 represents the median, which is the 50th percentile, it means that D4 will represent the 40th percentile.
Therefore, D4 will be the value that separates the first 40% of the data from the remaining 60%. To find the specific value of D4, you would need the actual dataset and calculate the 40th percentile using statistical methods or software.
