Front

What does a weak negative correlation indicate in a graph?

Back

A weak negative correlation indicates that as one variable increases, the other variable tends to decrease slightly, but the relationship is not strong.

Front

What is the range of a graph?

Back

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

Front

How do you interpret a correlation coefficient of -0.19?

Back

A correlation coefficient of -0.19 indicates a weak negative correlation between the two variables.

Front

What does the slope in a linear regression equation represent?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

What does a correlation coefficient of 0.07 indicate?

Back

A correlation coefficient of 0.07 indicates a weak positive correlation between the two variables.

Front

Define correlation in statistics.

Back

Correlation is a statistical measure that describes the extent to which two variables change together.

Front

What is a strong negative correlation?

Back

A strong negative correlation means that as one variable increases, the other variable decreases significantly.

Front

What is the difference between weak and strong correlation?

Back

Weak correlation indicates a slight relationship between variables, while strong correlation indicates a strong relationship.

Front

What does it mean if the correlation coefficient is close to 0?

Back

If the correlation coefficient is close to 0, it indicates that there is little to no linear relationship between the two variables.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0, representing the starting point of the line on the graph.
