In this activity, students adjust the median and standard deviation of a skewed Gaussian distribution. Then they can create a histogram from that distribution. This activity allows students to explore the idea of a skewed distribution. This activity includes supplemental materials, including background information about the topics covered, a description of how to use the application, and exploration questions for use with the java applet.

CCSS.Math.Content.6.SP.A.2: Common Core State Standards for Mathematics

Understand that a set of data collected to answer a statistical question has a distribution which can be described by its center, spread, and overall shape.

CCSS.Math.Content.6.SP.B.5c: Common Core State Standards for Mathematics

Giving quantitative measures of center (median and/or mean) and variability (interquartile range and/or mean absolute deviation), as well as describing any overall pattern and any striking deviations from the overall pattern with reference to the context in which the data were gathered.

CCSS.Math.Content.HSS-ID.A.1: Common Core State Standards for Mathematics

Represent data with plots on the real number line (dot plots, histograms, and box plots).

CCSS.Math.Content.HSS-ID.A.2: Common Core State Standards for Mathematics

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.
