Experimental Design

Review of experimental design and vernacular

QuestionAnswer
Used when the experiment has exactly two treatment conditions, subjects are paired off based on similarities - or act as their own "pair." Within each pair, each treatment is randomly assigned. Remember! Randomization occurs ONLY within the pairs. matched pairs design
________ occurs when control is not present in the experimental design. This happens when the researcher does not account for a variable that may have influenced the responses. The data collected in this experiment can't be used to draw conclusions. confounding
_______________ bias occurs when subjects are unwilling or unable to participate in a survey. nonresponse
When a subject responds to a treatment that is really neutral as if they have received an actual treatment, we call that the ___________ _____________. placebo effect
When certain members of the population are not represented in the sample, we call that ___________________. undercoverage
Used when the researcher divides the sample into subgroups based on a particular criteria, then assigns treatments randomly within the subgroups. randomized block design
The researcher has NO CONTROL over any treatment or response but instead only records data. observational study
When every member of the population is just as likely to be chosen as another. Every possible sample size n is equally likely to be chosen. SRS (simple random sample)
In general ____ occurs when the results favor a certain outcome. bias
_____ is when we ensure in our experimental design that multiple experimental units will receive each treatment. replication
_________________ reduces bias and (hopefully) reduces the effect of lurking variables by spreading those variables out among the treatment groups. randomization
