The following is the frequency distribution table;

Weights of the maximum temperature frequency

0-50 6

(0-50) 5

(51-100) 5

(101-150) 4

(151-200) 7

(200-250) 3

The brackets represent the fact that the variables corresponding to the maximum temperature (TMAX) are negative values.

Q2 (2nd Quartile) -78

Q3(3rd Quartile) -17

Maximum 39

There are no possible outliers on the dataset.

The value from your data that represents the top 20% is approximately -19.62.
