Test I (Midterm Exam in EDSTAT)

It is used to describe the basic features of the data in a study. It is used to present quantitative descriptions in a manageable form.

• Sampling techniques

• Inferential statistics

• Descriptive statistics

• Statistics

The group or portion of a population on which information is obtained, preferably selected in a such a way that it represents the population.

• Sampling

• Sample

• Data

• Variables

It affects the relationship between the independent and dependent variables by modifying the effect of the intervening variable/s.

• Control Variable

• Extraneous Variable

• Intervening Variable

• Moderator Variable

It provides a system for ranking observations from most to least or least to most.

• Continuous Data

• Discrete Data

• Ordinal Data

• Interval Data

Facts, observations, and information that come from investigations.

• Data

• Variable

• Sampling

• Statistics

Every element in the target population or universe [sampling frame] has equal probability of being chosen in the sample for the survey being conducted.

• Probability Sampling

• Population

• Non-probability sampling

• Sample

The process of randomly selecting intact groups, not individuals, within the defined population sharing similar characteristics.

• Simple random sampling

• Stratified random sampling

• Systematic random sampling

• Cluster sampling

The process whereby the researcher selects a sample based on experience or knowledge of the group to be sampled called “judgment” sampling.

• Convenience sampling

• Purposive sampling

• Quota sampling

• Snowball sampling

A method of probability sampling in which the population is divided into different subgroups and samples are selected from each of them.

• Multistage sampling

• Systematic sampling

• Stratified sampling

• Cluster sampling

The process of including whoever happens to be available at the time…called “accidental” or “haphazard” sampling.

• Criterion sampling

• Convenience sampling

• Intensity sampling

• Convenience sampling
