Mr Hardknuckles Class Marks

Mr Hardnuckles gave his class an algebra test. These are their marks. 2, 5, 7, 6, 8, 5, 3, 8, 9, 7, 6, 6, 8, 7, 4, 9, 5, 6, 6, 4, 7, 6, 4, 7, 6, 2, 6, 7, 6. Draw a Frequency Table for this data Do you know how to tally? Write this list of marks into your book.

Frequency Table 2, 5, 7, 6, 8, 5, 3, 8, 9, 7, 6, 6, 8, 7, 4, 9, 5, 6, 6, 4, 7, 6, 4, 7, 6, 2, 6, 7, 6. Score Tally Frequency How many students sat the test?

Draw a Bar Graph. Bar Graph of Marks On a bar graph the bars don’t touch each other. Label axes frequency score Add bars

Max = _________ Min = ________ Range = ________ Mode = ______ Median = _____ Mean = ______ Averages Highest score Lowest score Max - Min Most common score Middle when ranked Add all the scores up then divide by how many
