Question

Dr. Joslyn is attempting to use children's test scores in reading to predict how many friends children make. The problem with his study is that the reading test scores lack _____ when it comes to measuring the number of friends a child makes.

Answer 1

Answer:

Validity

Explanation:

Validity is simply said to the state of soundness and cogency. Being reasonable, factual, true is being valid.

Validity is the state of being legally or officially binding or acceptable.

"It is the state of being authentic and correct.

In research generally Validity is an indication of how sound your research is.

It talks about the design and the methodology of your research. While in Data collection, Validity means that your findings truly represent the phenomenon you are claiming to measure. Valid claims are solid claims.

From the context, the Dr Joslyn's trying to use test scores to predict how many Friends a Child has is simply invalid. Because it lacks validity on all grounds.

One can't deduce the number of friends some has by their test scores.
