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:  

The mean is the simple average of all numbers in the list. There are total 16 numbers.

So, the mean will be:

answer: .64
