Unit 3: Data & Statistical Reasoning

the science of collecting, analyzing, interpreting, presenting, and organizing data to understand patterns, make predictions, and draw meaningful conclusions about a population or phenomenon

• Approximate

• Statistics

• Correlation

• Deterministic

a data point showing the relationship between two variables

• Bivariate Data

• Outlier

• Approximate

• Correlation

a graph of plotted data points that show the relationship between two variables

• Bivariate Data

• Line of Best Fit

• Scatter Plot

• Linear Model

a straight line that shows the trend of the given scattered data points on a graph. The slope of the line is used to predict the behavior of data and show progression. There should be an equal amount of points both above and below the line.

• Bivariate Data

• Line of Best Fit

• Scatter Plot

• Linear Model

when the points on a scatter plot follow a SOMEWHAT straight line pattern

• Bivariate Data

• Line of Best Fit

• Scatter Plot

• Linear Model

a mutual relationship among the data points; can be positive, negative, or no correlation

• Correlation

• Statistics

• Approximate

• Linear Model

a relationship between two variables in which an increase in the value of one variable is associated with an increase in the value of the other, indicating an upward trend or pattern

• Negative Correlation

• Positive Correlation

• Strong Correlation

• Weak Correlation

a relationship between two variables in which an increase in the value of one variable is associated with a decrease in the value of the other, causing a downward trend or pattern.

• Negative Correlation

• Positive Correlation

• Strong Correlation

• Weak Correlation

a situation where there is no consistent pattern or relationship between two variables, meaning changes in one variable do not reliably predict changes in the other

• Weak Correlation

• Strong Correlation

• No Correlation

• Positive Correlation

a relationship between two variables in which their values are close and consistently change together; data points ARE close together

• Weak Correlation

• Strong Correlation

• Negative Correlation

• Positive Correlation
