Question 4 Mean Median And Mode Of Ungrouped Data Exercise 18A

The daily minimum temperature recorded (in oF) at a place during six days of a week was as under:

Day Minimum Temperature
Mon 35.5
Tue 30.8
Wed 27.3
Thurs 32.1
Fri 23.8
Sat 29.9

Find the mean temperature.

Answer:

We know that

Mean temperature = Sum of temperatures/ Number of days

By substituting the values

Mean temperature = (35.5 + 30.8 + 27.3 + 32.1 + 23.8 + 29.9)/6

On further calculation

Mean = 179.4/6

By division

Mean = 29.9 F

Therefore, the mean temperature is 29.9 F.
