The following data represent what 18 people said when they were asked to estimate the crowd at a public gathering:

325 450 500 500 550 575 575 600 600

650 650 700 700 700 725 750 800 900

State the mean, mode, median

Mean:
325+450+500+500+550+575+575+600+ 600+650+650+700+700+700+725+750+800+900/18 = 625

Median: Is it 600 or 700-550=625? If so why? :S I don't understand it...

Mode: 700

Can someone verify if it is correct or wrong?

Thanks

  1. The median is the number between the two in the middle. Half way between 600 and 650 = 625.

  2. Just to clarify, 18/2= 9 therefore its in position 9 and 10? then add up and divided by two again? This is only for an even number of data right?

  3. Right.

    You could have added 600 and 650 and divided by 2 to get 625.
