Mean: a number or quantity having a value intermediate with the given data. It can be calculated as follows:
[tex]Mean=\frac{sum\text{ of }all\text{ data points}}{Number\text{ of data points}}=\frac{\Sigma x}{n}[/tex]In our case:
[tex]\text{Mean}=\frac{14+13+11+16+8+15+5+11}{8}[/tex][tex]Mean=\frac{93}{8}[/tex][tex]Mean=11.6lb[/tex]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.
[tex]5,8,11,11,13,14,15,16[/tex]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:
[tex]\frac{11+13}{2}=\frac{24}{2}=12[/tex]Therefore, the median is 12lbs.
Answer:
• Mean: 11.6lb
,• Median: 12lb
