When a study is said to be "Valid"....
It is thought to measure what it was supposed to measure
it is thought that the same or similar results should be achievable if repeated
The DV is supposed to have the desired impact on the IV
it is thought to be ineffective
You have developed a speaking proficiency test for English language learners. Upon analysis, you find that the test questions are ambiguous and do not effectively measure the intended speaking skills. Additionally, test-takers receive inconsistent scores upon repeated administrations. What can be said about this test?
Reliable but Not Valid
Valid but Not Reliable
Not Valid and Not Reliable
Valid and Reliable
A science test designed to measure students' understanding of physics concepts consistently produces the same scores when taken multiple times. However, it is found that the test is actually measuring students' mathematical skills rather than their understanding of physics. What can be said about this test?
Reliable but Not Valid
Valid but Not Reliable
Not Valid and Not Reliable
Valid and Reliable
the way a researcher selects participants from a population
Correlation
Sampling
Variable
Placebo effect
research method where the researcher observes the subject in a natural setting without interfering
Naturalistic Observation
Case Study
Longitudinal study
cross-sectional study
Method of intense study of just one individual:
Naturalistic Observation
Experimental Study
Case Study
Survey
research method in which data are collected from groups of participants of different ages and compares so that conclusions can be drawn about differences due to age
Naturalistic Observation
Case Study
Longitudinal study
cross-sectional study
research method in which data are collected about a group of participants over a number of years to assess how certain characteristics change or remain the same during development
Naturalistic Observation
Case Study
Longitudinal study
cross-sectional study
If I want to gather how all students are feeling about remote learning so far, which method would make the most sense?
Experimental
Naturalistic observation
Case study
Survey
A type of design where researchers DO manipulate or change some characteristic(s) of the situation and then measure to determine the effects
Ethical Design
Experimental Design
Naturalistic Observation
Correlational Design
the group to which an independent variable is applied
Single Blind
Double Blind
Experimental Group
Control Group
the group that is treated the same way as the experimental group except that the experimental variable is not applied
Single Blind
Double Blind
Experimental Group
Control Group
the measure of a relationship between two variable sets of data
Variable
Sampling
Correlation
Control Group

Positive Correlation
Negative Correlation
No Relationship
What kind of relationship?
Positive Correlation
Negative Correlation
No Relationship
A disadvantage of using correlational research is...
Sometimes the manipulation of variables is impossible
It cannot determine causation
It can only be used when measuring the effects of a change
Its difficult to keep the participant's identity confidential
In a study, injections of saline solution (which contains no chemicals) were shown to be quite effective for relieving pain. This is an example of
A.an experimenter effect.
B.a placebo effect.
C.the experimental effect.
D.an order effect.
Operational Definition
Clear and detailed statements about how you will measure the data collected about the variables.
The entire group of people or animals in which the researcher is interested.
A sample that has characteristics that are similar to those in the population.
A measure of the relationship between two variables.
The practice of patients and experimenter's assistants remaining unaware of which patients get real treatment and which patients get a placebo
Placebo Effect
Double Blind
Self-Fulfilling Prophecy
Single Blind
an experiment in which the participants are unaware of who recieved the treatment
Placebo Effect
Double Blind
Self-Fulfilling Prophecy
Single Blind
Population
The entire group of people or animals in which the researcher is interested.
A sample that has characteristics that are similar to those in the population.
Subjects in an experiment who are not subjected to the independent variable and may receive a placebo treatment.
Study in which the subject do not know if they are in the experimental or the control group.
This refers to the method of gaining enough participants that represent various backgrounds of people, allowing researchers to generalize results to the larger population:
Full sampling
Double-blind placebo experiment
Random sampling
Naturalistic study
Representative Sample
A sample that has characteristics that are similar to those in the population.
Subjects in an experiment who are not subjected to the independent variable and may receive a placebo treatment.
The entire group of people or animals in which the researcher is interested.
Study in which the subject do not know if they are in the experimental or the control group.
