State Objectives MA perform operations with integers (e.g., addition, subtraction, multiplication, division MA perform operations with integers (e.g., addition, subtraction, multiplication, division MA solve application problems involving measures of central tendency (mean, median, mode) and dispersion (range) from data, graphs, tables, and experiments using appropriate technology. MA solve application problems involving measures of central tendency (mean, median, mode) and dispersion (range) from data, graphs, tables, and experiments using appropriate technology. MA collect, organize, graphically represent, and interpret data displays including: frequency distributions, line-plots, scatter plots, box and whiskers, and multiple-line graphs.
