General
Quantifying observations is called _______ .
__________ is foundation of quantitative methods.
What is Measurement?
Match the followings with appropriate question.(a-Whom?, b-What?, c-How?,d-Where?)
1-variables of interest
2-Appropriate survey tool
3-context
4-subject samples
1-b
2-c
3-d
4-a
Variables of interest doesn't need to be specified and be kept separate from variables of non-interest.
True or False
False
Name one of the quantitative methods used in evaluation studies.

Subject of interest in PER have been well defined and have a universally agreed-upon set of variables associated with them.
True or False
False
This is True for Physic Studies. For PER, there is no consensus on definitions of the constructs.
if the mean and median are close in value, then the data distribution is somewhat skewed.
True or False
False.
Symmetric
What is the difference between experimental design and quasi-experimental design.
Experimental Design: Randomly assigned individuals
Quasi-experimental Design:Randomly assigned groups
Rasch Model assumes that a person's score on an item is manifestation of a true score that is inherent to the person.
True or False
False.
CTT does.
The number of students in this class.
What is 8?
Name one of the scales of quantitative data.
Nominal Data
Ordinal Data
Interval Data
Ratio Data
Calculating mean values is always suitable for nominal/ ordinal data
False.
In practical applications ordinal data are often approximated to interval data if a normal distribution is assumed.
it is possible to calculate the minimally sufficient sample size for each group with the help of free online programs.
True or False
True.
G*Power Analysis or A Priori Sample Size Calculator
Circle the correct measurement.
In CTT / Rasch measurement , person ability and item difficulty estimates are sample independent.
Rasch
How many days are in one year?
365
Quantitative data in PER are mostly nominal or ordinal.
True or False
True
The larger the sample is, the better the estimate for the population is, and therefore ______ the standard error is.
Smaller
1-Repeated t -test
2-Mc Nemar test
In PER, which one of the above tests is particularly useful for comparing students' performance on questions that are dichotomously scored(1-correct, 0-incorrect)
2-Mc Nemar test
Name one model used for Rasch Analysis.
Dichotomous Rasch Model, rating scale model, partial credit model
What does PER stand for?
Physics Education Research
Match the following research questions with appropriate type of PER Studies?( a-survey research, b-experimental/quasi-experimental studies, c-evaluation studies)
1-What is the average performance for students at the OSU on the Force Concept Inventory?
2-To what extend do the psychometric properties of the test items indicate that all questions measure the same construct as they are supposed to?
3-Do students interactive engagement classrooms hold more expert-like views about knowledge and learning, as measured by the MPEX, than those in traditional classroom?
1-a
2-c
3-b
High correlation does not necessarily indicate causal relationships.
True or False
True
Give two examples of common techniques in inferential statistics for comparison of two or more samples
The two sample t-test
One-way ANOVA(F-test)
Two-way ANOVA(F-test)
ANCOVA(F-test)
Chi-square test
Multiway frequency test
Name two sets of fit statistics in Rasch Analysis
Item fit statistics
Person fit statistics
What is the name of this course?
Advanced Study of Thinking, Learning,& Assessment in Science and Mathematics Education
