have a maths question thats very important please help i'd really appreciate it -
I have to statistically analyze wages of two salons - and show what these mean for the company. i did this by calculating the mean, mode, median and range the results were:
salon 1 mean = £287.50 mode = £300 median = £300 range = £450
salon 2 mean = £305.00 mode = £300 median = £300 range = £450
this is where i got stuck i don't know what to write about these results and what they show for the salons?? Like what does the median, mode and range show as they are the same?? and what does this mean for the salon? thank

I thought I already answered a very similar question or is it the same person posting again? I feel there is some mistake in the data as already pointed out. With range, median and mode being same, how the mean alone is changing? Unless the raw data is also presented, it is difficult to make sense.

The mean is affected by extreme values... for your data this basically translates to the fact that the data below 300 for salon 1 is grouped a little way from the middle ie low values pull the mean down. The reverse has happened for the other salon.

eg
1 ,1, 1, 1, 5, 6, 7, 8, 9, 10 will have a much lower mean than 1, 1, 3, 4, 5, 6, 7, 8, 9, 10 yet their medians, ranges and modes are all the same

Hope this helps
