How does a pie chart help form conclusions? A. plotting all of the observations B. showing a constant ratio with the trend line C. showing how data falls into categories with the relative wedge sizes D. showing quantity by category
it is a close race between A and D, i would thingk A because you can form a conclusion based on seeing all the observations on paper.
if you get it wrong...just tell your teacher and say that they are basically the same (that A and D are basically the same).
Hope that helped
