The population in a research study is...

• the whole group of research interest.
• the smaller group that has been chosen from the group of research interest.
• exactly the same as the sample.
• always smaller than the sample.

It is a brief descriptive coefficients that summarize a given data set, which can be either a representation of the entire or a sample of a population. It is called?

• Analysis

• Descriptive statistics

• Totality

• Description Theory

What is a branch of mathematics dealing with the collection, analysis, interpretation, and presentation of masses of numerical data?

• Algebra

• Calculus

• Statistics

• Geometry

A mathematical methods that employ probability theory for deducing (inferring) the properties of a population from the analysis of the properties of a data sample drawn from it. It is concerned also with the precision and reliability of the inferences it helps to draw. It is called?

• Inferential statistics

• Descriptive statistics

• Nominal statistics

• Correlation statistics

An information, especially facts or numbers, collected to be examined and considered and used to help with making decisions. It is called?

• Facts

• Data

• Input

• Information simulation

This research method is a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles

• Case Study
• Survey
• Observational
• Correlational
• Experiments

This research method is a technique for ascertaining the self – reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group.

• Survey
• Observational
• Correlational
• Experiments
• Case Study

This is a method of research where the researcher carefully and systematically observes and records behavior without interfering

• Observational
• Correlational
• Experiments
• Case Study
• Survey

This research method is a measure of the extent to which two variables change together, and thus of how well either variable predicts the other

• Correlational
• Experiments
• Case Study
• Survey
• Observational
