## Conclusion:

The results suggest that different soil conditions have a noticeable impact on the overall performance of the corn crop, with herbicide usage showing a possible difference.

## Question 2

Problem Description: This assignment investigates the impact of three different treatments on plant growth in terms of height, width, and weight.

## Results:

MANOVA: Wilks Test

## Conclusion:

The choice of treatment significantly affects plant growth, with Drug A and Drug B having the most pronounced impact on memory scores.

## Question 3

Problem Description: This assignment examines the academic performance of students from different parishes in Jamaica in the subjects of Science and Mathematics.

## Results:

MANOVA: Wilks Test:

## Conclusion:

The results suggest significant academic differences among students from different parishes in Jamaica, specifically in the subjects of Science and Mathematics.

## Question 4

Problem Description: This assignment explores the impact of different syntactic categories (nouns, verbs, adjectives, adverbs) on the number of words learned by students.

## Results:

Repeated Measures ANOVA:

 Within Subjects Effects Cases Sum of Squares df Mean Square F p η² ω² Words learned 50.000 3 16.667 25.000 <.001 0.862 0.545 Residuals 8.000 12 0.667
