What is a Hypothesis?

What is an Interview?

• Median- is the center score in a
distribution.
• Mode- The most frequent score in a
distribution.
• All are basic forms of statistics.
What is Measurement?
• The operation that turns data into numbers.
What is the Population
• The target group under investigation.
What is a Problem?
• The topic being investigated once it has
been refined.
What is a Range?
• The difference between the highest and
the lowest scores in a distribution.
What is a Research Question?
• A sentence or paragraph that explains
the purpose of a given investigation.
The purpose of this research was to study
………….
What is Random Sampling?
• Process used in research to draw a
sample of the population strictly by
change to be participants in a research.
What is Reliability?
• An index of the consistency of data or
test results; results should very nearly
be the same, time after time.
What is a Sample?
• A group selected from a much larger
population.
What is a Standard
Deviation?
• A term used in statistical analysis. A measure of
variation between the scores of a distribution and the
mean.
What is a Survey?
• A research tool that includes questions.
• It’s goal is to gain specific information.
What is a Theory?
• A set of propositions that explain the data.
What is Validity?
• The degree to which a measurement
instrument measures what it is intended
to measure (instrument)

has true and accurate findings
(research)
What is Internal Validity?
