Answer:
Modes of staff wages are £180 and £254.
Median of staff wages is £248.5
Mean of staff wages is £276.625
Step-by-step explanation:
Given list of staff wages is.....
£254 £254 £310 £276 £116 £90 £312 £180 £180 £536 £350 £243 £221 £165 £239 £700
Rearranging the data according to ascending order.....
£90 £116 £165 £180 £180 £221 £239 £243 £254 £254 £276 £310 £312 £350 £536 £700
The mode is the number repeated most often. This list has two values that are repeated two times, which are £180 and £254.
So, the modes are: £180 and £254
Median is the middle value in the list. As there are total 16 numbers, so the middle value will be the average of 8th and 9th numbers, which are £243 and £254 respectively.
So, the median will be: [tex](\frac{243+254}{2})=\frac{497}{2}=248.5[/tex]
The mean is the simple average of all numbers in the list. There are total 16 numbers.
So, the mean will be:
[tex]\frac{90+116+165+180+180+221+239+243+254+254+276+310+312+350+536+700}{16}\\ \\ =\frac{4426}{16}=276.625[/tex]
