Question

Find the mean, median, mode

x|f
4|3
5|9
6|5
7|2
8|7
9|5
10|3

I tried to make the table lol:)

Answer 1

I don't understand how to find the mean, median, mode with a table?

Answer 2

mean is the average of all the frequency divide by 7
median u have to rearrange from ascending order and just find the middle number, if there's is two you have to add them together and divide by two.
mode is the simply 5 because it has the most frequency and occurs the most

Answer 3

I only look at the frequency numbers for median and mean?

Answer 4

3 and 5 occur at the same time also for mode?

Answer 5

well mode ur still looking at the highest occurring frequency still, which is number 5 clearly.

Answer 6

the same amount I mean

Answer 7

nvm im confused

Answer 8

that has no impact on the mode at all.

Answer 9

we are only looking at the highest frequency and we can see that is "9" at number 5.

Answer 10

Mean = Sum(Value*Frequency)/(Total Frequency)

Mean = (4*3+5*9+6*5+7*2+8*7+9*5+10*3)/(3+9+5+2+7+5+3)

Mean = (12+45+30+14+56+45+30)/(3+9+5+2+7+5+3)

Mean = (232)/(34)

Mean = 6.8235

Answer 11

ur right.

Answer 12

No, there are 34 total values, not 7

Answer 13

To find the median, start at the top and count up to 17 (this is half of 34)


Then start at the bottom and count up to 17


You'll land at the same spot between x = 6 and x = 7


So the median is the average of these two: (6+7)/2 = 6.5
