Can anyone help with this question
4vir4ik [10]

Answer: A) x=6

Step-by-step explanation: my trick that i do with these questions are to just fill in the x's with the different choices that they give you.

so... first try out 6. fill in every x with a 6. so now, x isn't x anymore, it's 6.

(8-6)=2

9 times 2= 18

3 times 6= 18

this means that x would equal 6

if that first one doesn't work, try out the other ones. but this one works, so we know we have the right answer. i hope this helps with this problem, and i hope it helps with other problems like this too.

:)

Which term refers to a statistical value that is a measure of the spread or variation in the scores in a given data set?
IRINA_888 [86]

Answer:

A

Step-by-step explanation:

The dispersion refers to the overall spread of the data — how "disperse" it is across values.

The independent variable is what you manipulate in a study, whereas the dependent variable is what you measure.

Central tendency is another word for average.
