:)
i did these a couple of years ago and at first i was like WHAT!!!! but when i looked into it it was really easy :)
okay first : the 'mean' is easy all you need to do is add up all the numbers then divide by the amount there were for example: your sequence: 4 8 6 2 9. so... 4+8+6+2+10= 30
so there is 5 numbers in total so what you do next is 30 divided by 5 so the answer is 6....the mean is 6
next the Median:
all you do for the median is put the data in order then it is the middle value for example: 4 7 2 5 9 fist put them in order smallest to largest: 2 4 5 7 9 then choose the middle value which is 5.....the median is 5
and lastly:
the mode is the number that occurs most often in a sequence for example:
2 6 3 5 8 3 2 5 7 9 3 4 6 7 8 ...... 3 occurs most often therefore 3 is the mode.
easy :)
i hope this helped....good luck :) xxxx

the median and mode are but the mean is not
The median is 9 and the mode is 18 and the mean is 11
mean: 1.7 median:1.7 mode: none
Mean, median, and mode are all equal in a normal distribution.
The median and mode cannot be outliers. For small samples a mode could be an outlier.
