Answer:
The game developer tested by 24 participants and these 24 participants were divided evenly between the treatments and the required total number of possible replications combinations is 4.
Step-by-step explanation:
The Concepts and reason
The ANOVA can be used to analyze the data obtained from experimental or observational studies. A factor is a variable that the experimenter has taken for investigation.
A treatment is a level of a factor, and its experimental units are the objects of interest in the experiment. The variation between treatments groups captures the effect of the treatment and the variation within treatment groups represents random error not explained by the experimental treatments.
The replication means an independent repeat of each factor combination.
Fundamentals
The formula for replications is: Number of participants/number of cells
The total number of participants is: 24
The number of cells is: 6
The total number of participants in the game is 24 and the number of possible combination cells is 6
so,
Number of replications: Number of participants/number of cells
which is 24/6= 4
Therefore the number of replications is 4.
