With the Grade 7s, we are moving into some work that is becoming a little more challenging. They are now understanding that the idea of the Mean refers to a set of numbers that is balanced out. In the case of an average of 8/10, consider the following image:
|This student scored the same mark on all 4 tests. A mark of 8/10. The total number of marks is 32 (8x4)|
In an example from today's lesson, we used the same idea of a person having 4 tests, but the marks varied.
As you can see, the range of marks was from 5-10 creating a range of 5.
There is no mode.
But the mean remain 8/10. Observe the calculations in yellow.
There has been a considerable amount of time provided in class for the completion of the work listed below.
