Question

each of the 8 cats weighed 14,13,11,16,8,15,5,11find the mean, median weights round to nearest 10th if needed mean: lbsmedian: lbs

Answer 1

Mean: a number or quantity having a value intermediate with the given data. It can be calculated as follows:

`Mean=\frac{sum\text{ of }all\text{ data points}}{Number\text{ of data points}}=(\Sigma x)/(n)`

In our case:

`\text{Mean}=(14+13+11+16+8+15+5+11)/(8)`
`Mean=(93)/(8)`
`Mean=11.6lb`

Median: value separating the lower half from the higher half. To calculate this parameter we have to order our data from the lowest to the highest value.

`5,8,11,11,13,14,15,16`

In this case, as there are an even pair of numbers, the middle value is 11 and 13. Thus, we have to calculate the average of these:

`(11+13)/(2)=(24)/(2)=12`

Therefore, the median is 12lbs.

Answer:

• Mean: 11.6lb

,

• Median: 12lb
