Question

calculate the median, given the following data
Mid Value :15 25 35 45 55 65 52
Class frequency :10 25 44 48 50 52​

Answer 1

Answer:

same as that i answer in previous question see in my id

Answer 2

Median is 150

Explanation:

• Arrange the data in ascending order:

Mid Value             Class frequency

15                                10

25                               25

35                               44

45                               48                            

55                               50

65                               52

• Computing the cumulative frequency:

Mid Value             Class frequency         Cumulative Frequency (CF)

15                                10                                10

25                               25                               35

35                               44                                79

45                               48                                127

55                               50                                177

65                               52                                229

So,

• The total (n) is 229, which is odd then the median is (n + 1 / 2)th observation:

• Median = (229 +1) / 2

                      = 300 / 2

                      = 150

• Therefore, the median is 150
