can someone please highlight the difference between these two tests. When should one be used over the other?
The F Test and T Test are both statistical tests used to compare the means of two groups. However, the F Test is used for comparing the variances of two groups, while the T Test is used for comparing the means of two groups.
An F Test should be used when you want to compare the variances of two groups. This is useful in determining if the two groups have similar amounts of variability or if one group has significantly more variability than the other.
A T Test should be used when you want to compare the means of two groups. This is useful in determining if the two groups have significantly different averages or if any observed differences are due to chance.
The F Test produces an F statistic and a corresponding p-value. If the p-value is less than a chosen significance level (usually 0.05), then the variances of the two groups are significantly different. If the p-value is greater than the significance level, then there is not enough evidence to conclude that the variances are different.
The T Test produces a t-statistic and a corresponding p-value. If the p-value is less than a chosen significance level (usually 0.05), then the means of the two groups are significantly different. If the p-value is greater than the significance level, then there is not enough evidence to conclude that the means are different.
