Tracy looked for a scientific study that summarized the literature on ways to lose excess weight by changing the size of food containers, but found no recent studies.  So she decided to conduct one herself.  She used PsychInfo and other search engines to find every study that examined excess weight loss and altered containers, and used statistics to mathematically average the results of all of the studies.
B.	Harold found a fantastic study that supported the hypothesis that smaller plate size results in less calories eaten. Harold decided to perform the same study, but to also examine the impact of obesity level (slightly obese, moderately obese, severely obese) on smaller plate size resulting in less calories eaten.
C.	Stacy recently read about a health researcher who was caught making up data to support his theory that moving unhealthy foods out of sight decrease consumption of those foods. So she decided to conduct the same exact study that this researcher did to see if she would get the same results.
D.	Jasmin knew that several studies supported the theory that smaller containers will result in less things taken, but she wanted to see if it would occur in daily life. So Jasmin conducted a study in which she decreased the size of plates and bowls in 10 households. She then tracked each household in terms of calories consumed.

Answer 1

(A) meta analysis

Explanation:A way of mathematically averaging the effect sizes of all the studies that have tested the same variables to see what conclusion that whole body of evidence supports.

(B)Ecological validity

Explanation:

The extent to which the tasks and manipulations of a study are similar to real-world contexts

(c)Replication-plus-extension

Explanation:

A replication study in which researchers replicate their original study but add variables or conditions that test additional questions.

(D)Direct Replication

Explanation:

A replication study in which researchers repeat the original study as closely as possible to see whether the original effect shows up in the newly collected data.
