A ___________________ is a way of organizing data from two categorical variables in order to investigate the association between them.
Categorical variable
Two way table
Bivariate data
Association
A ___________________ is a characteristic of individuals in a population that can take on different values.
Variable
Slope
Y-intercept
Statistic
A ___________________ is a graph that displays data points for two sets of data.
Two way table
Scatter plot
Relative frequency
Residual
The initial or “beginning” value of a situation (where the line crosses the y-axis) is called the ___________________.
Linear association
Y-intercept
Slope
Line of best fit
A relationship between two numerical variables is a ___________________ if an increase in the data for one variable tends to be paired with a decrease in the data for the other variable.
Strong relationship
Weak relationship
Negative relationship
Positive relationship
In statistics we say that there is an ___________________ between two variables if the two variables are statistically related to each other; if the value of one of the variables can be used to estimate the value of the other.
Residual
Clustering
Association
Outliers
A relationship between two numerical variables is a ___________________ if the data is tightly clustered around the best fit line.
Positive relationship
Strong relationship
Negative relationship
Weak relationship
Two variables have a ___________________ when a line cannot be reasonably drawn through data points because the points would not all stay close to the line.
Linear association
Non linear association
Negative relationship
Positive relationship
A ___________________ is a variable that takes on values which can be divided into groups or categories.
Bivariate data
Two way table
Association
Categorical variable
A scatter plot has ___________________ when data points form distinct groups.
Residual
Correlation coefficient
Clustering
Outliers
The ___________________ is a number between -1 and 1 that describes the strength and direction of a linear association between two numerical variables.
Correlation coefficient
Clustering
Outliers
Residual
The ___________________ travels through the middle of the points the closest.
Line of best fit
Slope
Linear association
Y-intercept
A relationship between two numerical variables is a ___________________ if the data is loosely spread around the best fit line.
Negative relationship
Strong relationship
Positive relationship
Weak relationship
A relationship between two numerical variables is a ___________________ if an increase in the data for one variable tends to be paired with an increase in the data for the other variable.
Strong relationship
Positive relationship
Negative relationship
Weak relationship
The _________ is the difference between the y-value for a point in a scatter plot and the value predicted by a linear model.
Residual
Outliers
Clustering
Correlation coefficient
A scatter plot has ___________________ when there are data points that do not fit the general pattern of the majority of the data.
Correlation coefficient
Clustering
Outliers
Residual
The ___________________ is the steepness of a line; the rate of change.
Y-intercept
Slope
Linear association
Line of best fit
Two variables have a ___________________ when a line can be reasonably drawn through the points of the graph and the majority of the points follow the line closely.
Negative relationship
Linear association
Non linear association
Positive relationship
Two pieces of data variables being compared at the same time are called ___________________.
Categorical variable
Two way table
Association
Bivariate data
A ___________________ is a version of a two-way table in which the value in each cell is divided by the total number of responses in the entire table or by the total number of responses in a row or a column.
Relative frequency
Scatter plot
Residual
Two way table
A ___________________ is one in which a change in one of the variables causes a change in the other variable.
Positive relationship
Negative relationship
Causal relationship
Linear association
