Sociology Research Methods: Crash Course Sociology
Today we’re talking about how we actually DO sociology. Nicole explains the research method: form a question and a hypothesis, collect data, and analyze that data to contribute to our theories about society.

Algebra 62 - Gauss-Jordan Elimination with Traffic Flow
In this lecture we examine one application that can be solved by a system of linear equations with four or more variables, modeling and predicting the flow of traffic through a network of streets. Examples are given showing how the model...

Natural Experiments
How do natural experiments differ from Field or Laboratory experiments? Are there different types and what does this research method give to psychologists that other methods don't? This film examines these questions in the context of...

Algebra 63 - Gauss-Jordan Elimination with Curve Fitting
This lecture examines a useful mathematical application that can be solved by using a system of linear equations with four or more variables - finding a polynomial function whose graph passes through a given set of data points. We see...

Functions of equations - IS IT A FUNCTION
👉 Learn how to determine whether relations such as equations, graphs, ordered pairs, mapping and tables represent a function. A function is defined as a rule which assigns an input to a unique output. Hence, one major requirement of a...

Given two points on a graph find the slope using slope triangle
👉 Learn how to find the rate of change from graph. The rate of change is the rate at which y-values are changing with respect to the change in x-values. To determine the rate of change from a graph, a right triangle is drawn on the graph...

Variations in Assumptions - Sensativity Analysis
A sensitivity analysis is used to test how variations in specific factors affect an outcome. The assumptions employed as part of the situational analysis are generally based on historical information, hypotheical contexts, and constancy
