Educational research methodology questions.

The type of descriptive statistics displaying how concentrated  data are around a single value. This types of descriptive statistics  is measured by:

1. The kurtosis index
2. The skew index
3. Dispersion(variability) of data
4. Central tendency

It is the type of research intended for developing and testing theories and hypothesis for generating fundamental knowledge and theoretical understanding about basic human and other natural processes:

1. Evaluation research
2. Basic research
3. Applied research
4. Quantitative research

It is a characteristic feature of research based on valid procedures and principles

1. Empiricism
2. Logical
3. Analytical
4. Replicability

A set of interrelated concepts, definitions, and propositions that explains or predicts events or situations by specifying relations among variables.

1. Research
2. A theory
3. Approach
4. Hypothesis

The following are examples of ontological questions except

1. What is the form and nature of reality?
2. What is there that can be known about it?
3. What are the characteristics of things that exist?
4. What is the nature of the relationship between the knower and what can be known?

A research design that attempts to establish cause-effect relationships among the variables of the study that already exist between or among groups of individuals is called:

1. Experimental research design
2. Causal-comparative research
3. Correlational research
4. Descriptive research

It is a type of test which produce a score that tells how individuals performance compares with other individuals

1. Norm reference tests
2. Domain-reference test
3. Standardized tests
4. Individual versus group tests.

In nominal measurement the numerical values just “name” the attribute uniquely with which the ordering of the cases is well implied.

T-Tests are used to test if the difference of means from two independent groups is statistically significant.

Regression is a more accurate way to test the relationship between the variables compared with correlations since by displaying the goodness of fit and the statistical testing for the variables.
