1. Which one of the following is among the things to remember when creating figures?

a. Use a lot of text

b. All graphs communicate several ideas

c. Do not label anything – allow the reader to figure it out

d. Maintain the scale of the graph

2. If you have a distribution of 50 scores, and you want 10 intervals, what should be the size of your class intervals?

a. 50

b. 25

c. 10

d. 5

option A is incorrect because using a log text is not recommended as it makes it too untidy or hard to read and see the data

option B is incorrect because we know that not all graphs communicate several ideas as there are some graphs which only provide one idea.

option c is incorrect because not labeling anything means we are not providing ready to interpret graph to reader which makes it unprofessional.

option D is correct because we must maintain the scale of the graph, as it makes graphs easy to understand and more appealing to the reader

we have a score of 50 and we need to make 10 intervals

so, size of class interval = (distribution of 50 scores)/(number of intervals)

setting the values, we get

size of the class interval = (50/10) = 5

so, the correct size of the class interval is 5

option D is correct
