Question 1

Randomization of test units is a part of &#8230;&#8230;&#8230;&#10;A)Pretest&#10;B)Posttest&#10;C)Matching&#10;D)Experiment

Accepted Answer

Randomization of test units is a fundamental aspect of designing an experiment. It ensures that each test unit has an equal chance of being assigned to any given treatment group, which helps to eliminate selection bias and confounding variables, thereby increasing the validity of the experimental results.

Question 2

The numerical description that describe sample may be expected to differ from those that describe population because of random fluctuations inherent in sampling process.&#10;A)Sampling design&#10;B)Non-probability sampling&#10;C)Sampling error&#10;D)Probability sampling

Accepted Answer

Sampling error is the correct answer because it refers to the difference between a statistic derived from a sample and the true value of the parameter in the population. This difference arises due to the random fluctuations inherent in the sampling process, as not all members of the population are included in the sample.

Question 3

In each population element has a known and equal chance of selection.&#10;A)Purposive sampling&#10;B)Quota sampling&#10;C)Stratified sampling&#10;D)Simple random sampling

Accepted Answer

In simple random sampling, every member of the population has an equal chance of being selected, which ensures that the sample represents the population as closely as possible without bias.

Question 4

is the evidence that the instrument, techniques, or process used to measure concept does indeed measure the intended concepts.&#10;A)Reliability&#10;B)Replicability&#10;C)Scaling&#10;D)Validity

Accepted Answer

Validity is the measure that ensures an instrument, technique, or process accurately measures the concept it is intended to measure.

Question 5

Experimental design is the only appropriate design where relationship can be established&#10;A)Strong&#10;B)Linear&#10;C)Weak&#10;D)Cause and Effect

Accepted Answer

Experimental design is specifically tailored to establish cause-and-effect relationships by manipulating one or more variables and observing the effect on some outcome.

Question 6

On which of the following, scientific knowledge mostly relies?&#10;A)Logical understanding&#10;B)Identification of events&#10;C)Prior knowledge&#10;D)All of the given options

Question 7

Which of the following refers to research supported by measurable evidence?&#10;A)Opinion&#10;B)Empiricism&#10;C)Speculation&#10;D)Rationalism

Accepted Answer

Empiricism is the theory that all knowledge is derived from sense-experience and supported by observable and measurable evidence, distinguishing it from theories based on speculation or opinion.

Question 8

All of the following are true statements about action research, EXCEPT;&#10;A)Data are systematically analyzed&#10;B)Data are collected systematically&#10;C)Results are generalizable&#10;D)Results are used to improve practice

Accepted Answer

Action research focuses on solving specific problems within a particular context, making its results less generalizable compared to other research methods that aim for broader applicability.

Question 9

A review that only demonstrates familiarity with an area is rarely published but it often is part of an educational program is which type of review?&#10;A)Integrative reviews&#10;B)Theoretical reviews&#10;C)Self-study reviews&#10;D)Historical reviews

Accepted Answer

Self-study reviews are typically designed to demonstrate familiarity with a subject area, often as part of an educational program, rather than contributing new knowledge or insights for publication.

Question 10

Accepted Answer

Extraneous variables are variables that are not related to the purpose of the study, but may affect the dependent variables.

Question 11

When the dependent variable is not free from the influence of extraneous variable,the relationship is known as&#10;A)Interrogative&#10;B)Exceptional&#10;C)Confounded&#10;D)None of the above

Accepted Answer

The answer of When the dependent variable is not free...
