Students also re-engage in the major work of the grade, particularly their work with ratios and proportions, when they use proportional reasoning to estimate population characteristics based on sample statistics. — Display numerical data in plots on a number line, including dot plots, histograms, and box plots.

All of these understandings will support seventh-grade students in their work in this unit. Worksheet 1.1-1.3 . — Informally assess the degree of visual overlap of two numerical data distributions with similar variabilities, measuring the difference between the centers by expressing it as a multiple of a measure of variability.

Grab the TEKS-Aligned Statistics Unit. These online tests are designed to work on computers, laptops, iPads, and other tablets. Use calculators, spreadsheets, and tables to estimate areas under the normal curve. Throughout the unit, students reason about data, make connections, and defend their reasoning by constructing arguments (MP.3). <>/Metadata 780 0 R/ViewerPreferences 781 0 R>> Find the difference in ranges from the girls (top graph) to the boys (bottom graph). �̅�Rj�#��C�#[�'�i�c��泈d%�d4��tY4sp��\p@ �x�x��x�d"[��+G�dJQ�͈i��,��S{��s��3�ܔ@�^"��l5��ekx9��yx��T��*�zd��-a!��춭Z�}��Z��zg=��%6�^?F�@%��h��D.�yc��+��F��%D�"�9�2��"�sȊ�$P&��(�� ($�P��2��Ai�Kf��ùfP��o�!��3�XFU*��#�4W>,O�C�@بxk�� iBAQ�pů��ME 4�xwԨ��$?��5��-e~�z��ǆ~Q!h@�=�x�f I have carefully crafted this exam to reflect the STAAR test as closely as possible in regards to difficulty level spreads and Reporting Category allocations, with one exception.

Here, you can find links to different tests and quizzes suitable for 7th grade students. Use relative frequencies calculated for rows or columns to describe possible association between the two variables.
