1. to the right of the data table, create a graph that would best represent this data. make sure to include a title, x and y axis titles, units of measurements, as well as anything else that your graph may need.
2. what is the independent variable?
3. what is the dependent variable?
4. is there a relationship being showed? if so, what is the relationship?

percentage of students letter grade in mr. wetmores class

1. what is the most common grade in my class?
2. what is the least common grade in my class?
3. based on the graph, do you think mr. wetmores class is difficult? why?

Explanation:

Step1: Identify independent variable

The variable that is controlled or changed is sunlight received daily. So, the independent variable is sunlight received daily (hours).

Step2: Identify dependent variable

The variable that depends on the independent - variable is the height of the sunflower. So, the dependent variable is height of sunflower (inches).

Step3: Determine relationship

As the amount of sunlight received daily increases, the height of the sunflower generally increases. There is a positive relationship between the two variables.

Step4: Analyze pie - chart for grades

In the pie - chart for grades, the largest slice represents the most common grade and the smallest slice represents the least common grade. If the majority of students have lower grades (like C, D, F), the class can be considered difficult.

For the sunflower data:

Answer:

1. Sunlight received daily (hours)
2. Height of sunflower (inches)
3. Yes, there is a positive relationship. As the amount of sunlight received daily increases, the height of the sunflower generally increases.

For the grade data:

1. The most common grade is the one with the largest percentage in the pie - chart (e.g., if B has 45%, B is the most common grade).
2. The least common grade is the one with the smallest percentage in the pie - chart (e.g., if A has 15%, A might be the least common grade depending on other values).
3. If the majority of students have lower grades (e.g., C, D, F have a large combined percentage), then Mr. Wetmore's class can be considered difficult because many students are not achieving high grades.
