Question

The stem and leaf plot shows the length in inches) of the eleven fish, caught during a fishing contest. What is the median weight of the fish

Answer 1

The median is the data that is exactly in the middle position.

Since the steam and leaf plot is already organized from least to greater we can count the number of data there is.

For this we count the number of leafs there are on the plot

There are 11 leafs on the plot which means there are 11 data.

To find the median we use the formula:

`M=x_{((n+1)/(2))}`

where M is the median and n is the number of data.

`(n+1)/(2)=(11+1)/(2)=(12)/(2)=6`

The median is at position 6 from least fo greater.

The median is at stem 1 and leaf 6

The median weight of the fist is 16.
