PLEASE MARK MY ANSWER AS BRAINLIEST
Mean = Sum of observation / Number of observation
Mean = 26 + 25 + 40 + 36 + 50 + 45/6
Mean = 222/6
Mean = 37
Ascending order = 25,26,36,40,45,50
n = 6(even)
Median = (n/2)th term + (n+1/2)th term / 2
Median = 3rd term + 4th term / 2
Median = 40 + 36 / 2
Median = 76 / 2
Median = 38
Found median too :)
