D4.5.1 between-groups design and a within-subjects designComparing and contrasting a
In a between-groups design, every study participant is only in one group or condition
while in a within-subjects design there is a likely participant connection in the independent
variable levels or conditions to the other independent variable levels or conditions (Morgan et al.,
2020). Also, in a between-groups design, different participants will be testing every condition to
expose every participant to a single user interface while in a within-subjects design, the same
participant will test all the user interfaces or conditions (Raluca, 2018).
D4.5.2. The information about variables, levels, and design one should keep in mind in
order to choose an appropriate statistic
For one to choose an appropriate statistic, the number of variables should be checked in
the research hypothesis or question. If the variables are two, a bivariate statistic can be used and
if the variables are three or more, the complex statistic can be used (Morgan et al., 2020). For
