"Today the student took summative practice and graded tests in her online course for the unit "Using Graphs to Analyze Data." The topics covered in this unit are: bivariate data, box and whisker plots, circle graphs, central angle, data clustering, frequency, histograms, interquartile range, line plots, linear and nonlinear relationships, mean, mode, median, outlier, quartiles, range, scatter plots, stem and leaf plots, trend lines, 2-way charts and Venn diagrams. She has made the calculation, interpreted the graphs, chose which graphs match data sets, and which type is best for given situations. On the 6-question practice test the student scored 83%. After a short break, the student worked on the graded test of 20 questions, including multiple choice and 3 short-answer. She demonstrated excellent understanding and using a calculator, got 16 out of 17 answers correct. The online teacher will grade the 9-point short answer portion. She is enjoying her successes and has strong prior knowledge. She has strengthened her recall of vocabulary and learned some new skills and concepts: "of" means multiply, percent is part divided by total times 100, negative numbers and subtraction are the same thing!"
