Five friends compare their marks in a French test. See the table below:
Name | Mark |
---|---|
Shabana | \[{41}\] |
Bea | \[{54}\] |
Liam | \[{79}\] |
Dave | \[{26}\] |
Ed | \[{65}\] |
What is the mean mark?
Mean \(=(41 + 54 + 79 + 26 + 65) \div 5\)
\[= 265 \div 5\]
\[= 53\]
Notice that the mean does not have to be any of the given data values.
A die is thrown \(10\) times. These are the results:
\[3,~5,~1,~2,~6,~4,~2,~5,~6,~1\]
What is the mean score?
To find the answer, add the values together and divide the total by the number of values:
Mean \(= (3 + 5 + 1 + 2 + 6 + 4 + 2 + 5 + 6 + 1) \div 10\)
\[35 \div 10 = 3.5\]
