Draw a diagram of the experimental design corresponding to the sv and df chart below.
SV df
rows 4
columns 4
treatments 4
residual 12
TOTAL 24
Answer is below let me know if it is correct, and I do not know how to draw it and input the numbers or letters into a 5×5 Latin square?? for the experimental design. Can someone do it with the numbers or letters in an actual Latin square and show me and break it down so I understand, I am having difficulties with this.
The table shows the degrees of freedom (df) for an experimental design with four levels of a single independent variable, known as a one-way ANOVA (Analysis of Variance). The independent variable is the factor being manipulated or varied in the experiment, while the dependent variable is the variable being measured or observed. The degrees of freedom are the number of independent pieces of information used to estimate a statistical parameter.
The total degrees of freedom (dfTotal) is the sum of the degrees of freedom for all sources of variation in the experiment, which is equal to the total number of observations minus one.
dfTotal = N – 1
where N is the total number of observations, which is 24 in this case.
dfTotal = 24 – 1 = 23
The degrees of freedom for the treatments (dfTreatments) is the number of levels of the independent variable minus one.
dfTreatments = k – 1
where k is the number of levels of the independent variable, which is also 4 in this case.
dfTreatments = 4 – 1 = 3
The degrees of freedom for the residual (dfResidual) is the total degrees of freedom minus the degrees of freedom for the treatments.
dfResidual = dfTotal – dfTreatments
dfResidual = 23 – 3 = 20
Finally, the degrees of freedom for the rows (dfRows) and columns (dfColumns) can be calculated using the following formula:
dfRows = r – 1
dfColumns = c – 1
where r is the number of rows and c is the number of columns, which are both 4 in this case.
dfRows = 4 – 1 = 3
dfColumns = 4 – 1 = 3
