Answer:

4

Step-by-step explanation:

Mean is another way to say the average of a set of numbers. To find the average you need to add all the numbers in the set together, and then divide by the amount of numbers that where given.

In this case:

6 + 8 + 2 + 0 + 4 + 5 + 3 = 28

there are 7 numbers given in the set, so you divide 28 by 7 to get your mean.

28 / 7 = 4

Answer:

4

Step-by-step explanation:

To find the mean of a set of numbers, you add up all the numbers and then divide them by the amount of numbers there are.

So, let's add up these numbers.

6 + 8 + 2 + 0 + 4 + 5 + 3 = 28

Now, there are a total of 7 numbers, so we divide 28 by 7.

28 / 7 = 4

Therefore, the mean of this data set is 4. I hope this helps! Have a lovely day!!

f(x)= -2x+1 {-2,0,2,4,6}

If x=-2, then -2(-2)+1 = 5

If x=0, then -2(0)+1 = 1

If x=2, then -2(2)+1 = -3

If x=4, then -2(4)+1 = -7

If x=6, then -2(6)+1 = -11

D. Coefficient of Correlation

Step-by-step explanation:

The name itself "Coefficient of Correlation" involves the word correlation, meaning relationship between two things.  

The coefficient of Correlation is used to determine how strong a relationship is between two variables.

The formula of Coefficient of Correlation gives a value between -1 and 1. Moreover, it helps to plot a graph showing the strength of relationship.

1 : A strong positive relationship

-1: A Strong negative relationship

0: No relationship at all

One of the most used formula is Pearson Correlation Coefficient Formula, picture of which is attached. X and Y represent two different set of datas.

<u>Note: </u>

The other terms are defined as :

Coefficient of Determination : Square of correlation between predicted scores and actual scores. It usually ranges from 0 to 1 .

Standard deviation of estimate : represents the amount of variation among a set of values .

Standard Error of estimate : It is the measure of dispersion of sample means around population means.
