Explanation / Answer

6)

Option A)

Reputation of the author

Explanation:

In order to reviewing articles certain information will be recorded. In meta data analysis , Meta-analysis is a statistical procedure consider different types of data from multiple studies, so that each type of study can be scrutinise properly and meta data is used to identify the common effect when the treatment effect (or effect size) is consistent from one study to the next. It also identifies the reason for the variance, if there has any variation of data from one study to another.

So it is important to conduct a metadata analysis that the effect of size of information which main parameter for data analysis, moderator variable play an important role to identify the variation , number of participant also play an important role ,as observation shows whether the data’s are statistically significant. As we know larger sample size leads to normal distribution. Basic information regarding the author, title of the article and name of the journal identify where and who did the work and from the title it shows the nature of the study.

Therefore the reputation of the author is less important compare to other parameters.

7) Option E)

Essential importance.

Explanation:

In meta data analysis , Meta-analysis is a statistical procedure consider different types of data from multiple studies, so that each type of study can be scrutinise properly and meta data is used to identify the common effect when the treatment effect (or effect size) is consistent from one study to the next. It also identifies the reason for the variance, if there has any variation of data from one study to another. So it is a complicated study design.  

Therefore uses of computer is essential, to store , analyse and retrieve the data and make proper inference on the basis of each study.

8)

Option E)

The procedures used in the study were complicated and hard to understand.

Explanation:

In meta data analysis, Meta-analysis is a statistical procedure consider different types of data from multiple studies. So it is a complicated study design. Therefore to summarized the text book , it is important to mention the following:

The number of studies analyzed was large to satisfy the normality assumption of a data set. Moderator variable which leads to appropriate interpretation of the model, Effect size of the test and test criteria was calculated in order to decide the appropriate policy from the complicated study. A bibliography for the article shows different sources of information and helps to build the theoretical concept of the study.

Therefore , The procedure used in the studies were complicated and hard to understand is a false statement.

9)

Option E)

B and C are true.

Explanation: As the approaches of metadata analysis is a new technique and its require many article published on a specific topic but in reality it has less article, and hence a small number of metadata analysis is found in many of the Kinesiology journal.

10)

Option E)

B, C and D are all criticism.

In meta data analysis, Meta-analysis is a statistical procedure consider different types of data from multiple studies. So it is a complicated study design. So it has some criticism which is not support by the metadata analysis and also due to lack of information and infrastructure it creates los of criticism.

It also combine the god and bad study to identify the proper conclusion, and also not always applicable to study each problem, it also combine the study of different article or participant which are not similar in participants and procedure.

Hence B, C and D all are the criticism of meta data analysis.
