Question

1. The distribution of an average tends to be normal, even when the distribution from which the average is computed is decidedly non-normal is an example of:

the Central Limit Theorem.

2. The type of research that focuses solely on data-related results is referred to as:

mixed-methods research.

3. When a test or assessment measures the expected universe of knowledge it is supposed to measure, it is said to have:

criterion-related validity.

4. An independent study was conducted to determine whether math scores on average were significantly higher for 5th grade girls than for 5th grade boys at the same school. Data indicated a difference with a probability of less than .05 (p < .05). Assuming that all aspects of the study were conducted appropriately, we can conclude that:

math scores for the 5th grade girls on average were significantly higher than 5th grade boys.

there was no difference in math scores between 5th grade girls and 5thgrade boys

math scores for the 5th grade girls on average were lower than the 5thgrade boys.

there is insufficient information to make a proper determination.

Explanation / Answer

1:

The distribution of an average tends to be normal, even when the distribution from which the average is computed is decidedly non-normal is an example of:

the central limit theorem

2:

The type of research that focuses solely on data-related results is referred to as:

quantitative research

4:

Since p-value is less than 0.05 so we reject the null hypothesis.

math scores for the 5th grade girls on average were significantly higher than 5th grade boys.
