Dot plot graphs

This week in Rimu, we were working on Dot plots and bar graphs. It is probably an easier way to do a graph. it is very simple. make an equation that needs a chart. then get a chart and make the percents in dots. Here is an example :

Robert, a Year 8 student at Roosevelt Middle School, usually goes to bed
around 10:00 p.m. and gets up around 6:00 a.m. to get ready for school.
That means that he gets about 8 hours of sleep on a school night.
He decided to investigate the statistical question: How many hours per
night do 6th graders usually sleep when they have school the next day?


Robert took a survey of other Year 8 children and collected the following
data to answer the question:
7 8 5 9 9 9 7 7 10 10 11 8 8 8 12 6 11 10 8 8 9 9 9 8 10 9 9 8

Robert decided to make a dot plot of the data to help him answer his
statistical question. Make a dot plot with Robert’s data.

This is what it would look like. Now I want you to try one of your own. If you like this idea, please leave some feedback. See you next time!
