Understand that straight lines are not a good fit for data that clearly shows a curved pattern, and analyze patterns in bivariate data that are categorical by creating, analyzing, and interpreting two-way tables.
Analyze and describe patterns of association between two variables in a scatter plot, including whether the association is linear or nonlinear, and identify positive, negative, or no association.
Construct and interpret a linear function (e.g., a line of best fit) to model relationships between two variables that exhibit a linear association, and assess the model's fit.
Use the equation of a linear model to solve problems and interpret the meaning of the slope and y-intercept in the context of the data.

In Grade 8, statistics focuses on understanding and analyzing relationships between two variables. Students learn to identify patterns in data, make predictions, and interpret real-world information.
Grade 8 statistics topics include investigating patterns in bivariate data using scatter plots, analyzing categorical data with two-way tables, and modeling linear relationships. Students also learn to interpret slope and y-intercept in context.
Encourage your child to look for data patterns in everyday life and discuss what they mean. Practice interpreting graphs and tables together, and reinforce the concepts of correlation and linear modeling.
Statistics can be challenging as it requires both mathematical skills and critical thinking to interpret data. However, with clear explanations and plenty of practice, most Grade 8 students can master these concepts.
