Question 1

These are basic tools researchers used to gather data for specific research problems

Answer 1

Research Instruments

Question 2

common research instruments

Answer 2

• performance tests
• questionnaires
• interviews
• observation checklist

Question 3

factors that need to be decided before
constructing a research instrument

Answer 3

1. Type of instrument
2. reasons for choosing the type
3. description and conceptual definition of its parts

Question 4

Characteristics of a Good Research Instrument

Answer 4

• concise
• sequential
• valid and reliable
• easily tabulated

Question 5

Have you tried answering a very long test, and because of its length, you just pick the answer without even reading it? A good research instrument is _______ in length yet can elicit the needed data.

Answer 5

Concise

Question 6

Questions or items must be arranged well. It is recommended to arrange it from simplest to the most complex. In this way, the instrument will be more favorable to the respondents to answer.

Answer 6

Sequential

Question 7

The instrument should pass the tests of ______ and _______ to get more appropriate and accurate information.

Answer 7

Validity and Reliability

Question 8

Since you will be constructing an instrument for quantitative research, this factor should be considered. Hence, before crafting the instruments, the researcher makes sure that the variable and research questions are established. These will be an important basis for making items in the research instruments.

Answer 8

Easily tabulated

Question 9

Ways in Developing Research Instrument

Answer 9

• adopting an instrument
• modifying an existing instrument
• researcher made his own instrument

Question 10

Common Scales Used in Quantitative Research

Answer 10

Likert Scale
Semantic Differential

Question 11

Types of Validity of Instrument

Answer 11

• Face Validity
• Content Validity
• Construct Validity
• Concurrent Validity
• Predictive Validity

Question 12

It is also known as “logical validity.” It calls for an initiative judgment of the instruments as it “appear.” Just by looking at the instrument, the researcher decides if it is valid.

Answer 12

Face Validity

Question 13

It is done by checking the statements or questions if this elicits the needed information. Experts in the field of interest can also provide specific elements that should be measured by the instrument.

Answer 13

Content Validity

Question 14

It refers to the validity of instruments as it corresponds to the theoretical construct of the study. It is concerning if a specific measure relates to other measures.

Answer 14

Construct Validity

Question 15

When the instrument can predict results similar to those similar tests already validated, it has ______.

Answer 15

Concurrent Validity

Question 16

When the instrument is able to produce results similar to those similar tests that will be employed in the future. This is particularly useful for the aptitude test.

Answer 16

Predictive Validity

Question 17

refers to the consistency of the measures or results of the instrument

Answer 17

Reliability

Question 18

It is achieved by giving the same test to the same group of respondents twice. The consistency of the two scores will be checked.

Answer 18

Test-retest Reliability

Question 19

It is established by administering two identical tests except for wordings to the same group of respondents.

Answer 19

Equivalent Forms Reliability

Question 20

It determines how well the items measure the same construct. It is reasonable that when a respondent gets a high score in one item, he will also get one in similar items.

Answer 20

Internal Consistency Reliability

Question 21

Steps in Making a Research Instrument

Answer 21

1. Gather indicators from literature review or experts.
2. Make instrument items from the indicators you gathered.
3. Decide on the type of responses you want. (e.g. dichotomous, rating scales)
4. Write the instructions for your instrument above the items
