#2
What is the key characteristic of a ratio scale?
Ranking and equal intervals
True zero point
Ordered categories
No meaningful zero point
#3
In measurement scales, what does the term 'mutually exclusive' mean?
Categories are distinct and do not overlap
Categories can overlap with each other
Categories are dependent on each other
Categories are interchangeable
#4
What is the key feature of a nominal scale?
Equal intervals
Ordered categories
True zero point
Categories with no inherent order
#5
In survey research, what is a potential disadvantage of using open-ended questions?
Limited participant engagement
Difficulty in data analysis
Bias in responses
Limited depth of information
#6
What is the primary characteristic of an ordinal scale?
Equal intervals between adjacent points
Absolute zero point
Ordered categories with no fixed intervals
Numerical values with meaningful zero points
#7
Which type of validity involves comparing a test to other measures that assess the same construct?
Content validity
Criterion-related validity
Construct validity
Concurrent validity
#8
Which measurement scale allows for ranking and equal intervals but lacks a true zero point?
Nominal scale
Ordinal scale
Interval scale
Ratio scale
#9
What is the primary limitation of using a ratio scale?
Inability to establish equal intervals
Absence of a true zero point
Difficulty in ranking items
Lack of precision
#10
Which of the following is an example of a ratio scale?

#11
What is the main advantage of using an interval scale over an ordinal scale?
It allows for ranking
It has equal intervals
It is easier to interpret
It provides a true zero point
#12
In research, what does internal validity refer to?
The extent to which the results can be generalized to other populations
The accuracy with which the study measures what it intends to measure
The consistency of the measurement instrument
The degree to which the study eliminates alternative explanations for the observed relationship
#13
What is the purpose of a Likert scale in survey research?
To measure nominal data

#14
Which type of validity focuses on whether a measurement accurately represents the entire domain it is supposed to cover?
Face validity
Content validity
Criterion-related validity
Construct validity
#15
In experimental research, what is the purpose of random assignment?
To ensure external validity

#16
In survey research, what does response bias refer to?
Systematic differences in how a variable is measured
Participants' reluctance to respond truthfully
The lack of variability in responses
Errors in data entry
#17
What is the primary purpose of a pilot study in research?
