- Purpose: One of the most commonly made decisions is based on comparing the means of multiple conditions. Significance tests for comparing means are critical in the decision making process. In this assignment, you will practice how to use t tests and ANOVA tests to compare the means of multiple conditions under one independent variable in different experiment design (between-group and within-group) Tasks: Please write an R script that performs the following operations in the order listed. At the beginning of each task, write a comment marking the task number. Name the file as: lab6-<your last name>.R ANOVA tests 8. Import the 'iris.csv' dataset. Browse and understand the data in each column 9. Compute descriptive statistics and create boxplot for sepal length and species. 10. Select the appropriate test to determine whether there is significant difference in sepal length between the three species. Follow the steps of ANOVA analysis. Make sure you check whether the assumptions are…arrow_forwardthe only data that should b epresented as numerical values are those that represent numbers. data that represent categories should never be presented as numerical values.

If Lynn plays on the team, she is busy. Lynn does not work full time. Therefore, Lynn is busy.arrow_forward
- assign(self, assignment:Assignment) -> AssignmentResult: """ This function is to simulate the process of the student receiving an assignment, then working on the assignment, then submitting the assignment and finally receiving grade for the assignment. This function will receive an assignment then a grade should be calculated using the following formula: grade = 1 - (Student's current energy X Assignment difficulty level). The min grade a student may receive is 0% (0) After the grade is calculated the student's energy should be decreased by percentage difficulty. Example if the student has 80% (.8) energy and the assignment is a difficultly level .2 there final energy should be 64% (.64) = .8 - (.8 * .2). The min energy a student may have is 0% (0) Finally the grade calculated should be stored internally with in this class so it can be retrieved later. Then an Assignment Result object should be created with the student's ID, the assignment…arrow_forwardCreate the following variables that can be used to store values. Use the naming conventions as outlined in the Algorithms/Pseudocode Guidelines document in the course resources section of the course. 1. test grade for student test 2. total of all test grades added together 3. the average for the test grades Create an assignment statement that sets the value of the variable you created to store the value of all test grades added together to zero. You may refer to Table 6.1 in Chapter 6 for examples. Create an input statement to input the value for the first test grade for the variable you created. Create an algorithm that will obtain the test grade for three students, add the test grades together, calculate the average of the test grades, and output the average. Use a count-controlled loop to create the algorithm. Use the information from your answers to questions 3, 4, and 5 in the creation of your algorithm. Also use information and examples from Chapter 6…arrow_forwardplease describe how you would create the program and why, referencing which data structure you would use.arrow_forward
