Given data in ascending order:
50, 60, 65, 70, 70, 80 85, 90, 95, 95
∴ Number of observations (n) = 10 (i.e., even)
∴ Median is the average of middle two observations
Here, 5th and 6th numbers are in the middle position
∴ Median = (70 + 80)/2
∴ Median = 150/2
∴ The median of the weights of tomatoes is 75 grams.
