My Maths results

For Maths we have been doing Basic facts stage 5 and stage 6. We had to turn it into a stem and leaf Graph.
Here is a bar graph showing my results.

The day I got the lowest was day nine because I got my stage five questions in the wrong place. I had been practicing between day 3 and 4 when I was doing my homework. The highest score I got was on day 4, 7, 8.
Range: 88%-52%=36%
Median: 72%
