The Pie Chart is NOT an appropriate choice to represent the information.
Why do you think it's not appropriate?
It is not appropriate as these numbers could be rounded off (If you see: The figures are rounded to the nearest whole number at the bottom left of the image aboe) , and it is also very difficult for people to see, especially if you need some numbers right away. (You'll have to calculate here and there.)
What makes you think the 3 remaining graphs are appropriate?
The other 3 graphs usually gives more actual numbers. Not rounded ones like Pie Charts.
-PS: I have no time to do the second one: By the end of elearning... I hope. I have to run along for CCA-
Based on your first reason, based accuracy in representating data due to rounding off:
ReplyDeleteIf the figures given, after calculating result, are in exact figures (where no rounding off is necessary), would PIE graph still be appropriate then?
Points to ponder...
What kind of information does PIE chart usually provide?
Does each type of graph serve a different purpose or it doesn't matter?
