Psychology Vocabulary Quiz
Preview:
an observation technique in which one person is studied in depth in the hope of revealing universal principles
A. Confidentiality
B. Case study
C. Experiment
D. Hypothesis
a simulated or otherwise medically ineffectual (fake) treatment for a disease or other medical condition intended to deceive the recipient. Often given to the control group in an experiment.
A. Scatterplot
B. Placebo effect
C. Skewed distribution
D. Placebo
in an experiment, the group that is not exposed to the treatment: contrast with the experimental group ad serves as a comparison for evaluation the effects of the treatment
A. Debrief
B. Experimental group
C. Control group
D. Inferential statistics
when patients given a placebo treatment will have a perceived or actual improvement in a medical condition
A. Random assignments
B. placebo effect
C. placebo
D. Replicate
a group of procedures that summarize or describe a set of data. These procedures include the measurement of central tendency and measures of variability
A. Inferential statistics
B. Descriptive statistic
C. Illusory correlation
D. Measure of central tendency
When the researcher himself alters or changes the result of the study. For example, a teacher studying differences in math skills between boys and girls might spend more time teaching boys because he/she believes that boys are better at math
A. Operational definitions
B. Overconfidence
C. Observer bias
D. Random sample
a research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable). By random assignment of participants, the experiment aims to control for other relevant factors
A. Placebo effect
B. Mode
C. Experimental group
D. Experiment
the post experimental explanation of a study, including its purpose and any deceptions, to its participants
A. Descriptive statistic
B. Hawthorne effect
C. Debrief
D. Median
an ethical principle the research participants’ identity and information remain private in any research study
A. Confidentiality
B. Overconfidence
C. Theory
D. Validity
the tendency to overestimate how easy something might be or how long a task might take
A. overconfidence
B. Placebo effect
C. population
D. Replicate
in an experiment when neither the participants nor the researchers know who belongs to the control group and who belongs to the experimental group. Only after all the data have been recorded (and in some cases, analyzed) do the researchers learn which individuals are which.
A. Single-blind procedure
B. Inferential statistics
C. Double-blind procedure
D. Measure of central tendency
(normal curve) a symmetrical, bell-shaped curve that describes the distribution of many types of data; most scores fall near the mean (68% fall within one standard deviation of it) and fewer and fewer near the extremes
A. Normal distribution curve
B. Random sample
C. Distribution curve
D. Observer bias
refers to how spread apart the scores of the distribution are or how much the scores vary from each other. There are four major measures of variability, including the range, interquartile range variance, and standard deviation
A. Measure of central tendency
B. Measures of variation
C. Null hypothesis
D. Operational definitions
the outcome factor; the variable that may change in response t manipulations of the independent variable
A. Independent variable
B. Dependent variable
C. Histogram
a statistical index of the relationship between two things (from -1 to +1)
A. Experimental group
B. Statistical significance
C. Correlation coefficient
D. Inferential statistics
a statement that is the opposite of the original hypothesis. Research must be compared to the null hypothesis (the opposite scenario) to see if any variance is in fact due to the independent variable
A. Null hypothesis
B. hypothesis
C. Inferential statistics
D. Overconfidence
established by the A.P.A, guidelines that outline what s acceptable and unacceptable for treatment of participants in research studies
A. Range
B. Ethics
C. Skewed distribution
D. Theory
in an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable
A. Statistical significance
B. Experimental group
C. Inferential statistics
D. Measure of central tendency
a factory other than the independent variable that might produce an effect in an experiment
A. Operational definition
B. Independent variable
C. Measures of variation
D. Confounding variables
a graph that shows the frequency between two things
A. Histogram
B. Hypothesis
C. Mode
D. Population
a statement of procedures (operations) used to define research variables. For example, human intelligence may be operationally defined as what an intelligence test measures. The operational definition must explain how the variable will be measured.
A. Debrief
B. Operational definitions
C. Experiment
observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation.
A. Skewed distribution
B. Theory
C. Social desirability bias
D. Naturalistic observations
techniques that allow researchers to make generalizations (or to infer) about the populations from which the samples were drawn.
A. Inferential statistics
B. Normal distribution curve
C. Descriptive statistic
D. Operational definition
the experimental factor that is manipulated; the variable whose effect is being studied
A. Informed consent
B. Dependent variable
C. Observer bias
D. Independent variable
type of descriptive statistic that is a single value that attempts to describe a set of data by identifying the central position within that set of data. These measures include mean ,median, and mode
A. Naturalistic observations
B. Measure of central tendency
C. Measure of variation
