ERM Student-led Activity 9

If we talk about the existence of dependence between two variables we are referring to...

• correlation

• causation

• degree of freedom

Which of these tests is not parametric?

• Pearson

• ANOVA

• Spearman

It is used for measurable on a continuous scale variables

• Chi square test

• Pearson's correlation

• T-test

What is the T-value?

• The result of comparing 2 means relative to their variability

• The number we use to determine statistical significance

• The number of observations in the data that are free to vary

If our p-value is greater than our alpha value...

• We reject the H0

• We fail to reject the H0

• Our result is statistically significant

If in an experiment we have 3 IV, with 2 factor levels each one, how many conditions do we have?

• 3 x 2

• 2 x 3

• 8

When do we use One-way ANOVA?

• When we have only 1 factor/IV with >2 levels and only 1 DV

• When we have >1 factor (with only 1 level) and only 1 DV

• When we have >1 factor (with multiple levels each) and only 1 DV

What is represented in this image?

• A normal distribution

• A T-distribution

• A F-distribution

“Factorial ANOVA” is just another way to refer to the “2-way ANOVA"

• True

• False

One-way ANOVA can calculate interaction effects

• True

• False
