Q2 = D5 = Median

Then what is D4 going to be?

I am talking about Deciles here

To determine the value of D4 (the fourth decile), we can use the following steps:

1. Start by arranging the data in ascending order.
2. Identify the position of the fourth decile using the formula: Position = (4/10)(n + 1), where n represents the total number of data points.
3. Check if the position is an integer. If it is not an integer, round it down to the nearest whole number. This will give you the index number of the value that represents the fourth decile.
4. Locate the value at this index number in the sorted data set. This value will represent the fourth decile (D4).
