a.

A population

b.

A sample

c.

Not significant enough

d.

None of the above

3. The ability of a test to produce the same measurements regardless of who administers it is:

	b.	reliability
	c.	validity
	d.	accuracy

4. The ability of a test to produce the same measurements from one day to the next is:

	a.	objectivity
	b.	reliability
	c.	validity
	d.	accuracy

Answer 1

1.post hoc tests are run to confirm where the differences occurred between groups, they should only be run when you have a shown an overall statistically significant difference in group means (i.e., a statistically significant one-way ANOVA result).

Ans=> a.specific mean differences after an ANOVA

2.If a researcher recruited and measured 40 people in a research study to look at adverse effects of a particular medical treatment, these 40 people are sample

Ans=>b.Sample

3.The ability of a test to produce the same measurements regardless of who administers it is validity

Ans=> c.validity

4. The ability of a test to produce the same measurements from one day to the next is: Reliability

Ans=>b.Reliability
