Why are reliability and validity important for assessment? how are content validity and criterion-related validity used to establish construct validity? support your position.

They help in the determination of the appropriateness and meaningfulness of the assessment

Step-by-step explanation:

The content validity helps to ascertain if the facets of the constructs are covered in the construct while criterion-related validity helps to determine how one of the construct predict the outcome of another measure in the outcome.

suppose we are measuring sleep, if the test does measure sleep then we say the test has a content validity. in other word, when a student takes a GRE, we can say we have a criterion related validity because GRE is a good predictor of student's performance in Graduate school.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16
