Fill in the Blank
Quantitative research design uses ________ data to explore a phenomenon.
Numeric
Identify a problem. Develop a research plan. Conduct the study. Analyze and evaluate the data. Communicate the results. Generate more new ideas.
6 steps to the scientific research method
The variable accounting for or "causing" the effect
Independent variable
The variable receiving the effect
The dependent variable
A quasi-experimental design where participants complete a survey asking for their impressions of a speaker before he gives a motivational speech and again after the speech. Participant ratings given in the survey are compared.
One-group pretest-posttest design
Participants complete a task and after completing the task are asked to complete a feedback survey indicating how difficult they felt the task was. This is a _________ type of quasi-experimental research design
One-group posttest only design
An experimental design than does not allow for broader generalization to a sample population
Single case research design
A research design without a a control group or manipulation
Nonexperimental research design
A study that changes across the lifespan by observing the same participants at different points in time.
A longitudinal design
An experiment design lacking one requirement of a true experiment
Quasi-experimental design
If the experimental group receives the treatment, the control receives the ______
Placebo
Having participants rate their response on a scale from 1 to 7
Self-report measure
A type of measurement in which researchers record physical responses of the brain or body
Physiological measure
Used to analyze the the mean difference between two-groups.
Two-independent sample t-test
It is the group that does not receive a treatment
Control group
The goal in ____________ research design is to minimize individual difference and something other than the manipulation from causing differences between groups.
Between-subjects experiment
The way participants are assigned to groups using a between-subject experimental design.
Random assignment
Randomization, manipulation, and control
The requirements of experimental designs
Statistical analysis used to compare differences in interval and ratio data between two or more groups in an experiment.
The one-way between-subjects ANOVA
Statistic used to make a decision regarding if an effect observed in a sample is also likely to be observed in the population from which the sample was selected.
Test statistic
___________ assignment ensures that participants are assigned to groups entirely by chance.
Random
A type of design in which different participants are observed in each group, or at each level of the factor.
Between-subject design
The ability to create two groups, one with a treatment and one without, and observe participant behavior
Control
The group that receives the treatment
Experimental group
the statistic that makes researchers more likely to conclude the difference between two groups is caused by manipulation.
Error variance (small)
