ANOVA: Analysis of Variance - Parametric One-Way Two-Way PostHoc

Based on the video, this is a type of inferential, parametric statistical tool for evaluating the differences of three (3) or more independent populations using hypothesis testing.

(a)  

The Analysis of Variance is used when data groups follow a normal distribution, variance are assumed equal, and (a)   sampling was used for all treatments.

ANOVA helps you find out whether the differences between groups of data are statistically (a)   .

The video discussed the different types of ANOVA. These were mentioned EXCEPT:

• One-Way ANOVA

• Two-Way ANOVA

• One-Way ANCOVA

In the video, what was the Independent Variable used in the One-Way ANOVA on brand product example?

(a)  

The video mentioned several groups/levels or treatments that were used in the One-Way ANOVA brand product example? All of these are included EXCEPT:

• wheat

• maize

• rice

• consumer

In the video, what was the 2nd Independent Variable used in the Two-Way ANOVA on brand product example?

(a)  

The video mentioned several groups/levels or treatments that were used in the Two-Way ANOVA on brand product example. These are included EXCEPT:

• Sweetened

• Unsweetened

• Calorie in Cereal

In the video, The ANOVA (a)   is a ratio of the Between Group Variation divided by the Within Group Variation.

The video explained that when the p-value is less than 0.05, then what would be our conclusion?

• Fail to Reject the Null Hypothesis

• Reject the Alternate Hypothesis

• There is a significant difference between the means,

• There is no significant difference between the means.
