Given : A student wants to find the number of hours SPENT by her on the computer every week. The student collects DATA for 40 weeks as follows:

0, 10, 20,6,6,2,10,5, 5, 10,0,6,5,20  , 20,10,10,20,1,6, 10,15,15,10,20,6, 6,6,5,10,15,15, 20, 20, 10,5,5,5,6,2

To Find : a) Construct a frequency distribution  table using classes 0-5, 5-10, etc

b) Construct a histogram for the data.​

Solution:

0, 10, 20,6,6,2,10,5, 5, 10,0,6,5,20  , 20,10,10,20,1,6, 10,15,15,10,20,6, 6,6,5,10,15,15, 20, 20, 10,5,5,5,6,2

20, 20  , 20 ,20, 15,15 20 ,15,15, 20, 20,

frequency distribution

0 - 5         5             0 0  1 2  2

5 - 10       15             5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6

10 - 15       9              10  10  10  10 10  10 10  10  10

15 - 20       4               15 15 15 15  

20 - 25       7              20 20 20 20 20 20

HISTOGRAMS. Histogram: a graphical display of data using bars of different heights. It is similar to a Bar Chart, but a histogram groups numbers into ranges . The HEIGHT of each bar shows how many fall into each range.
