-
Performing lots of t tests increases the chance of failing to reject a false null hypothesis
-
All of the above
Pregunta 2
Pregunta
The ANOVA statistic is calculated by __________
Respuesta
-
Multiplying the between groups variance by the within groups variance
-
Subtracting the between groups variance from the within groups variance
-
Adding the between groups variance to the within groups variance
-
Dividing the between groups variance by the within groups variance
Pregunta 3
Pregunta
You calculate an F ratio and get a value more than 1. How would you interpret this?
Respuesta
-
There is the less between groups variance than within groups variance
-
There is the same amount of between groups variance and within groups variance
-
There is no within groups variance
-
There is more between groups variance than within groups variance
