Question

Table 2 shows frequency distribution for variable p.рFrequency10385112144.6695157Table 2: Frequency distribution for pa) Calculate the mean value for p.b) Calculate the median value for p.c) Find out the mode value for p.

Answer 1

Step 1:

Draw a table to find the mean

Next, find the mean.

`\text{Mean = }(394)/(32)\text{ = 12.3125}`

Step 2: Median

The median is the middle number when the sets of data are arranged in ascending order.

8, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 11, 11, 14, 14, 14, 14, 15, 15, 15, 15, 15, 15, 15, 16, 16, 16, 16, 16, 16

Median is the mean of 14 and
