Ok so do you know what the term correlation means?

Answer 2

no

Answer 3

Answer 4

@Hero

Answer 5

Draw a line through as many points as possible and particularly be sure to make sure the line goes through the first and last points. Extend the line so that it crosses the x or y axis and a horizontal/vertical line as shown. Then find the slope of the line. You should be able to calculate a value that is approximately close to one of the given choices.

Answer 6

so 1?

Answer 7

What did you calculate for the rise and run?

Answer 8

i dont know how to do that

Answer 9

Rise/run

Answer 10

This is what corolation means

Answer 11

When two sets of data are strongly linked together we say they have a High Correlation. The word Correlation is made of Co- (meaning "together"), and Relation. Correlation is Positive when the values increase together, and. Correlation is Negative when one value decreases as the other increases.

Answer 12

Rise/run is your slope. You have to calculate your slope.
Now let me give u an example.
Rise is how much the line changes in the y-direction and run is how much in the x-direction,

So for this
Then for this example, we see that the run is 2 units (travels 2 units in x-direction) and the rise is -2 units because it travels 2 units DOWN in the y-direction,
Rise/run so -2/2 which gives a slope of -1

Answer 13

so 3,5 ?

Answer 14

Thats just a segment of a line btw, a line extends on forever on both sides so its fine if we look at a segment

Answer 15

Listen to @Ari1234442

Answer 16

Or @darkknight

Answer 17

alr, so lets look at the trendline that hero gave us
one point (0,3) and another point (4,5)
can you take the slope from here?
Remember that slope is rise/run. Calculate change of y over change of x

Answer 18

@Ari123442 is explaining what correlation is, which is what the asker needs to understand.

Answer 19

Yes, that is right do you get it?

Answer 20

ya

Answer 21

Ok good

Answer 22

Well if u have learned what correlation means you can scroll up now, i gave a response on slope. \[(y2-y1)/(x2-x1)\] is formula

Answer 23

Correlation In A Nutshell:
1. Is data positively related or negatively related?
2. Is the value of the correlation closer to -1, 0, or 1?

Answer 24

Answer those two questions, and you'll have your answer

Answer 25

negatively related

Answer 26

Positive

Answer 27

The direction of the slope should tell you whether it is negatively or positively related. Yes it is positive, correct. Now look at your answer choices. Which value is consistent with a positive correlation?

Answer 28

1

Answer 29

Exactly. You had it right earlier.

Answer 30

Good Job

Answer 31

thank you

Answer 32

Have a good day.
