Consider this continous date 3129232725232225212828141024301

Consider this continous date:

31,29,23,27,25,23,22,25,21,28,28,14,10,24,30,19,17,23,21,24,15,20,26,17,23,20

1)Create a 5 or 6 group frequency distribution for the data

2) create a frequency polygon for the data.

3) what is the median class for the data?

Solution

arrange the data in increasing order
10,14,15,17,17,19,20,20,21,21,22,23,23,23,23,24,24,25,25,26,27,28,28,29,30,31

3.
arrange the dat ain a
10,14,15,17,17,19,20,20,21,21,22,23,23,23,23,24,24,25,25,26,27,28,28,29,30,31
median is the average of the middle term = (23+23)/ 2 =23
