ANOVA is not an analysis of the standard deviations of the groups.
In large-scale projects, and especially in cases in which the data entry is performed by a
subcontractor, researchers utilize a data code book which identifies (1) the questions on
the questionnaire, (2) the variable name or label that is associated with each question or
question part, and (3) the code numbers associated with each possible response to each
question.
The moderator’s task in a focus group is to allow openness among the respondents and
to never try to focus them on some general area of interest.
Because we have two samples when testing the significance of the difference between
two percentages instead of the one that we worked with for a hypothesis test, the
standard error term is calculated differently, called the standard error of the difference
between two percentages.
