What is the linear regression equation?

Back

A linear regression equation is a mathematical formula that describes the relationship between two variables, typically in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you interpret the slope in a linear regression equation?

Back

The slope (m) indicates the change in the dependent variable (y) for each one-unit increase in the independent variable (x).

Front

What does it mean if data is skewed right?

Back

If data is skewed right, it means that the tail on the right side of the distribution is longer or fatter than the left side, indicating that there are a few high values.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified ranges (bins).

Front

How do you find the mean of a data set?

Back

Add all the data values together, then divide by how many values there are.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables, with points representing individual data points.

Front

What is the purpose of a trend line in a scatter plot?

Back

A trend line is used to show the general direction of the data points and can help predict values based on the relationship observed.

Front

What does it mean to calculate the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

What is the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest; if there is an even number of values, it is the average of the two middle values.

Front

What is the range of a data set?

Back

The range is the difference between the highest and lowest values in a data set.
