Examples/notes (2) fo two-proportion z testing are included, with calculator screenshots and formulas (pooled samples in Example2). Students are prompted to check conditions, interpret P-values, and write a conclusion in context.4 Practice Problems and an answer key are includedIf you like this actvity, please follow me on TPT! If you have any questions (or suggestions), please send me a note and I will try to respond asap. Thank you, Mary Landon

This assessment could also be used as independent practice or review. 11 probems, including 8 multiple choice (MC) and 3 free-response. Topics included: Mean, Median, Quartiles, IQR, rangeDot plot- analyze (MC)Box plots - analyze (MC), graph (free-resonse)2 way tables - analyze, find percents (MC and free-response) Frequency histogram - analyze (MC), graph (free-response)

This assessment includes the following topics 8 multiple choice problems: linear regression equations, strength of correlation, correlation coefficient (r-value), causal relationships 2 free-response problems: Analyze and apply linear regression (1) Use a graph and given r-value to determine strength and direction of a linear regression, identify outliers, and make predictions (2) Complete a linear regression, find the r value, and use the equation to

Graphs & Correlation - examples and descriptionsLinear Regression - writing an equation / 2 methods: (1) Graphing calculator (screenshots from TI- nspire) (2) Computer output Analyze data --- find an equation, use r and r^2 to determine strength, analyze a residual plotDescribe a correlation in contextUse regression model to make predictions ANSWER KEY on pg 5If you like this activity, please follow me on TPT - to receive notices about sales and new products.

I have used this as an introduction to 2-variable data and linear correlation (in Algebra and in Statistics). Students will interpret scatter plots, then construct a plot (#6, pg3).Page 4 may be printed separately and handed-out to include in their notes; this can be used as a reference guide.Answer Key is included on pg 5.If you like this activity, please follow me on TPT -- to get sale notices and info on new products!

Students will follow 5 steps to complete a Linear Regression using the TI-nspire (Example with screenshots on Pg1)They will display the data in a scatterplot on the calculator, write an equation for the regression, and use the correlation coefficient (r-value) to determine the strength of the correlation.4 practice problems, including NY State CC Algebra Exam problemsANSWER KEY included with activity

This is a hands-on calculator lab/activity. First students will simulate the growth of cancer sells using M & Ms. Then they will model exponential decay. Materials: Paper cups, M & Ms, paper towels (opt.) TI-nspire calculators, lab activity Day1: You may assign partners, so that one student follows steps (tosses M & Ms) and other student records results/data. Day2: Students will analyze their data; they use exponential regression on the calculator to generate equat

Good as a review/practice after completing a unit on data measures, probabilities, and distruibutions (7th grade) Includes: Statistics - mean, median, mode, range, and "MAD" Probability of random events Compound probabilities - independent, dependent events Tree Diagram Distributions - shape (symmetry) Dot plot, Mean Proportion

Probability Review includes: Independent and Dependent Events - 3 Tree Diagrams and Probabilities (compund events), with graphicsCalculating probabilities (rolling 1 die or a pair of dice)Probability Distributions - Dot Plots and Box Plots (look for symmetry)Calculating median, mean. and "MAD" for a set of data

Notes/Intro to Line of Best Fit Two examples - Analyze plots, describe correlations, find slope of a line, make predictions Two practice problems - Draw a scatterplot and a line of best fit, and use the line to make predictionsCreate an equation for a line of best fit, using the slope and y-interceptMake predictions, using line of best fitDescribe a relationship/correlation in context.Please follow me on TPT -- to get sale notices and info on new products!You can c

In this activity, students will follow calculator steps to enter 1-variable data into a spreadsheet and and calculate statistical values, including the mean and median/5-number summary.Students will apply the 5-Numer Summary values to complete a Box Plot ("Box & Whisker" graph)
