Math test on Monday

The data management test on Monday will cover the following topics:

Grade 5: 

mean and mode
discrete and continuous data (knowing the difference)
collecting and organizing data into graphs (bar graphs and broken line graphs)
describing trends in a graph


Grade 6:

mean, median, mode and range
discrete and continuous data (knowing the difference)
collecting and organizing data into graphs (double bar graphs and continuous line graphs)
describing trends in a graph

Sample Questions:

1. The weekly salaries of six employees at McDonalds are $140, $220, $90, $180, $140, $200. 
For these six salaries, find: (a) the mean (b) the median [grade 6 only] (c) the mode (d) the range [grade 6 only]


2. Andy has grades of 84, 65, and 76 on three math tests.  What grade must he obtain on the next test to have an average of exactly 80 for the four tests? [grade 6 only]
