You will create your table by using the data from your minimum to your maximum values. That is from 1 to 40. Label your table.

The 8 groups would then be split into sets of 5. Note how the first symbol is 'smaller than or equal to' / and the second symbol is just 'smaller than.'

Once you have the sets arranged put the data into the correct set.Note that I cannot 'score through' the first four to create the fifth number so have used a forward slash to indicate the fifth number.So the first row has two sets of 5 + 1 = 21. There will be 40 altogether : the 6 forward slashes included). Indicate them as 'score-throughs' when you transfer the information :

1<= x<6....................I I I I /  I I I I  / 1

6<= x<11..................I I I I / I I I I

11<= x<16................I I I I  / I

16<= x<21...............I I I I /

21<= x<26...............I I I I / I

26<=x<31

31<=x<36...............I I

36<=x<=40.............I
