How many more shares in a& d than shares in peer comms ltd. would you be able to buy with $500 in year 2?

Let's find out the mean and median as the first step:

The median would be: $30000 as it is the 32 and 33th place.

The mean would be:30000×62+125000×3÷(62+3)
=2235000÷65
≈$34384.615

We can then find that the mean would be a better data to summerise the data overall,as the median would only be able to show the salary of the 62 people,having being placed in 32 and 33th.

Hope it helps!
