In such a diagram, the total o all the given itms is equated to 360 degrees and the

degrees o angles, representing dierent items, are calculated proportionately. !he

entire diagram loo"s li"e a pie and its components resem#le slices cut rom a pie. !he

pie chart is used to show the #rea"$up o one continuos varia#le into its component

parts.

!he pie chart encompasses a circle o

360 degrees, which represents '00 o

the value o the continuous varia#le.

!hus, 3.6 degrees on the pie chart

represent ' o the total value o the

continuous varia#le #eing represented.

single pie diagram can represent only one continuous varia#le. /ence, in terms o

versatility o data representation, pie charts are less versatile than either o #ar

charts, &$y graphs orta#les. /owever, their utility is in the act that the presentation

o data is cleaner and it gives an immedaite idea o the relative distri#ution o the

continuous varia#le amongst dierent sectors.

!he ollowing e&ercise will ma"e the use o Pie$charts clear to you.
