1. Identifying & Interpreting Independent & Dependent Variables
Scientists answer questions by performing experiments that have an independent variable, a dependent variable and at least one control variable. By controlling, adjusting and measuring these variables, scientists find answers to their questions.
2. Simple Linear Regression: Definition, Formula & Examples
Simple linear regression is a great way to make observations and interpret data. In this lesson, you will learn to find the regression line of a set of data using a ruler and a graphing calculator.
3. Problem Solving Using Linear Regression: Steps & Examples
Linear regression can be a powerful tool for predicting and interpreting information. Learn to use two common formulas for linear regression in this lesson.
4. What is the Standard Error of the Estimate? - Formula & Examples
When you take measurements of some quantity in a population, it is good to know how well your measurements will approximate the entire population. In this lesson, learn how to calculate the standard error of your estimate and interpret your results.
