Causation vs. Association: What is the difference?

Back

Causation indicates that one event is the result of another, while association indicates a relationship between two variables without implying that one causes the other.

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

How do you convert an equation from standard form to slope-intercept form?

Back

To convert from standard form (Ax + By = C) to slope-intercept form (y = mx + b), solve for y.

Front

What is the slope of the line given by the equation y = 3/2x + 6?

Back

The slope (m) is 3/2.

Front

If a line has a slope of -2/3, what is the slope of a line perpendicular to it?

Back

The slope of a line perpendicular to it would be 3/2.

Front

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.

Front

How do you determine the range of a graph?

Back

To determine the range of a graph, identify the lowest and highest y-values on the graph.

Front

What is the y-intercept of the line y = (4/3)x - 5?

Back

The y-intercept is -5.

Front

What does it mean if two variables have a causal relationship?

Back

It means that changes in one variable directly cause changes in the other variable.

Front

What is an example of causation?

Back

An example of causation is: 'Increasing the temperature of the oven reduces the cooking time for a turkey.'
