QuestionIn an ANOVA, the "parts", attributes, or conditions of the independent variable are referred to as: variations levels treatment effects factors
Studdy Solution
STEP 1
What is this asking?
This question wants to know the name for the different parts of the independent variable in an ANOVA test.
Watch out!
Don't confuse "factors" (the independent variable itself) with its parts.
It's easy to mix them up!
STEP 2
1. Understand ANOVA
2. Define "Factor"
3. Define "Levels"
STEP 3
ANOVA stands for **AN**alysis **O**f **VA**riance.
It's a statistical test used to compare the means of **three or more groups**.
Imagine you're testing different types of fertilizer to see which one helps plants grow the tallest.
STEP 4
The **independent variable** is what you change or control – in this case, the type of fertilizer.
The **dependent variable** is what you measure – the height of the plants.
STEP 5
In ANOVA, the independent variable is called a **factor**.
So, in our plant example, the type of fertilizer is the **factor**.
STEP 6
The different *values* or *categories* within a **factor** are called **levels**.
If we're testing three types of fertilizer (e.g., Brand A, Brand B, and no fertilizer), then those are the three **levels** of the **factor** "type of fertilizer".
STEP 7
The correct answer is **levels**.
