Answer 1

Mode is which number occurs the most, so based on that, which number occurs most?

Answer 2

78

Answer 3

Try again, which number do you see the most?

Answer 4

sorry 77

Answer 5

Yes. So that knocks off two answer choices. The next easiest is Median. Do you know how to find median?

Answer 6

kinda im not good at math

Answer 7

That's okay, there's very little math involved, really. Okay, start by crossing out the least and greatest number, going back and forth until you find the middle. Tell me if you end up with one solid number, or two.

Answer 8

77

Answer 9

So which answer choice has A Median of 77 and a Mode of 77?

Answer 10

none

Answer 11

According to what you put up there, one of them does.

Answer 12

oh d

Answer 13

Ta da! you got it!

Answer 14

Answer 16

The chart shows donations that a few people have made to a new charity. A fundraiser wants to encourage people to increase their donations to the charity.

Donations
Donors Amount
Donor 1 $10
Donor 2 $30
Donor 3 $8
Donor 4 $8
Donor 5 $12

Which measure could the fundraiser use to encourage donors to increase their donations?

A.
Mean. The reason: The mean of this data is greater than either the mode or median and will tell donors the average of the amount people are giving.

B.
Median. The reason: It disregards the highest and lowest amounts and will be representative of donations the team members received.

C.
Mode. The reason: It gives the amount of the donations that two of the team members received.

Answer 17

I would probably go with Mean, here. If other donors see the average, they would probably want to be that, or go higher than average, making them increase it their donations

Answer 18

the first thing you need to do is line the numbers up from least to greatest, Example : if you had 9, 12 15 and 6 you would line them up like this , 6, 9 12 and 15

Answer 27

Okay, I'm really not good with box and whisker plots, but I'm pretty sure it's 12. There are twelve units in the space where it's boxed off, rather than just lines.

Answer 33

@iGreen @abb0t @fallenangelorchid @saifoo.khan please someone help

Answer 34

Sorry, my mom was asking me something. Yeah I'm here.

Answer 35

40 is the minimum, but it's not an outlier. An outlier is a point that isn't connected to the whole segment or a part of the boxes.

Answer 36

But the whole thing doesn't have any outliers, so it would be D, most likely.

Answer 39

I don't really know standard deviation, so you should probably ask someone else.
