descriptive correlational research design ppt

Correlational research is used to find out if there is a relationship between two or more variables and how strong that relationship is. Employs an experimental group versus control group design determined by random assignment . Activate your 30 day free trialto continue reading. K= 7 ! They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Looking back in time to detect causes or risk factors for the presence or absence of an outcome Example: Case-Control Studies Cigarette smoking lung cancer People with lung cancer = cases People without lung cancer = controls Differences between groups = smoking, Correlational Research Design One Group Designs: Single Group Descriptive design : no random selection of subjects Convenience or volunteer sample Examine characteristics of a single group Natural setting Measurements made about the group Subjects serve as own control Measure group X 1, X 2, or more Still one group EXAMPLE: Satisfaction surveys one group over 12 month time period - Use the resulting descriptions to draw conclusions about that groups satisfaction scores, Correlational Research Design One Group Designs: Time Dimension Interrupted Time Series Involves more than one pre and post test measurement Equal number of measurements before and after the intervention The time periods must be constant and equal Longitudinal Time Series Follows one group to examine and measure changes in same subjects over an extended time period, Correlational Research Design One Group Designs: Time Dimension Strengths Allows examination of sequences and patterns of change over both single time period Interrupted time periods Weaknesses Multiple measurements over an extended period Subject drop out Threatens instruments validity & reliability Distorted data Subject keeps a copy of the survey and duplicated responses Hawthorne effect, Correlational Research Design One Group Design: Summary Correlational No random assignment Characteristics of single sample Pre test/post test Time series or multi-variant Longitudinal, Non-experimental Quantitative Research Comparative Descriptive Design Describes variables & examines differences in 2 or more groups Occurs naturally in a setting No manipulation of variables Results obtained from the final analysis are frequently not generalized to a population. It is common to find researchers who treat quantitative variables conceptually as if they were categorical, but nothing is gained by this procedure and it should be avoided.
