The formula for Observed Score is; Observed score (X) = True score (T) + measurement error (e)

<h3>What is the observed score formula?</h3>

The formula for Observed Score is;

Observed score (X) = True score (T) + measurement error (e)

1) True score is the score that would be obtained if an individual took a test an infinite amount of times and those test scores were averaged. The concept of true score is theoretical because you can't give someone something an infinite number of times.

2) Standard error of measurement is the standard deviation of multiple test scores (how far the sample mean of the data is likely to be from the true population mean).

The less random error (e) in the measure, the more the observed score X approximates the true score T.

Thus;

Observed score = True Score + Error

Answer:

see below

Step-by-step explanation:

Usually, we're concerned about the relationship of y to x. Here, the question is asking you to consider the relationship of x to y.

The easiest way to find the answer to this one is to check the given explanations to see which is true. You can pretty much ignore the first row of the table and just look at the second row where x=5 and y=15.

it is NOT TRUE that x is 3 times y (5 is not 3 times 15)
it is TRUE that x is 1/3 of y (5 is 1/3 of 15)
it is NOT TRUE that x is 5 times y (5 is not 5 times 15)
it is NOT TRUE that x is 1/5 of y (5 is not 1/5 of 15)

_____

If you know your multiplication tables, you know that 15 = 3×5, so ...

5 = 15/3

5 = (1/3) × 15

The relationship of these numbers should not be a mystery.
