Make a frequency table using five classes class 3138 3946 47

Make a frequency table using five classes. class 31-38 39-46 47-54 55-62 63-70

Solution

Here we have to make a frequency table using 5 classes.

We need a data for this.

Suppose the data is,

69, 35, 56, 32, 43, 53, 60, 64, 37, 67, 59, 44, 57, 36, 45.

Suppose we ahve to make frequency table using these values and given classes.

In frequency table there are two columns classes and frequency.

The table we can make as follows,

There are total 15 observations.

When we arrange these observations in increasing order then they will appear as follows:

32 35 36 37 43 44 45 53 56 57 59 60 64 67 69.

So first class is 31 - 38 in that class we will see 4 observations.

similarly in the second class 39 - 46 there are 3 observations

In this way in the last class there are 3 observations.
