MAFS.912.S-ID.1.4  Use the mean and standard deviation data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate. Use calculators, spreadsheets, and tables to estimate areas under the normal curve.

MAFS.912.S-ID.1.2  Use statistics appropriate to the shape of the data distribution to compare center (median, mean) and spread (interquartile range, standard deviation) of two or more different data sets.

Learning Targets and Learning Criteria
  • These Learning Targets will be reviewed and tested this week.
  • use the mean and standard deviation of a set of data to fit the data to a normal curve

  • use the 68-95-99.7 Empirical Rule to estimate the percent of a normal population that falls within 1, 2, 3 standard deviations of the mean

  • recognize that normal distributions are only appropriate for unimodal and symmetric shapes

  • estimate the area under a normal curve using a calculator, table, or spreadsheet

    • identify and interpret the similarities and differences in the shape, center, and spread of a data set and within real-world context if given.

    • describe the center of the data distribution (mean or median).

    • choose the histogram with the largest mean when shown several histograms.

    • describe the spread of the data distribution (interquartile range or standard deviation).

    • choose the histogram with the greatest standard deviation when shown several histograms.

    • choose the box-and-whisker plot with the greatest interquartile range when shown several box-and-whisker plots.

    • understand and be able to identify which measure of center and spread are appropriate depending of the shape of the distribution.

    • recognize the mean moves towards a skew or extreme value.

    • Students will identify similarities and differences in shape, center, and spread when given two or more data sets.


    • identify the outliers for the data set.

    • predict the effect an outlier will have on the shape, center,and spread of a data set.

    • decide whether to include the outliers as part of the dataset or to remove them.

    • use their understanding of normal distribution and the empirical rule to answer questions about data sets.

Classroom Activities

Any student with an “I” incomplete last quarter must complete all missing assignments by the end of this week.  Please see Mrs. Barnes to arrange after school time to complete any missing tests, remediation, or corrections.
