Jahrell's Statistical Investigation "Favourite Cars"


I have used Google Slides to present my graphs that I created in my Statistics Investigation about what cars are the most popular.



      Favourite Cars Summary
I think the gauge graph is the best but because the data numbers were lower it was harder to see the results.

The median value is 3 as it is in the middle.
1, 1, 3, 3, 4, 7, 14

The mean or average is 4.3 41+1+3+3+4+4+7+14 = 33   33➗8=4.3

The range is the difference between the lowest and highest value.
1, 1, 3, 3, 4, 7, 14      14 - 1 = 13

The mode is the most frequent value.
1, 1, 3, 3, 4, 7, 14   so 1 and 3 are the most frequent mode.
