Grade 6: Probability and Statistics

6.PS.1

The student will apply the data cycle (formulate questions; collect or acquire data; organize and represent data; and analyze data and communicate results) with a focus on circle graphs.

6.PS.1.a

Formulate questions that require the collection or acquisition of data with a focus on circle graphs.
(Content unavailable)

6.PS.1.b

Determine the data needed to answer a formulated question and collect the data (or acquire existing data) using various methods (e.g., observations, measurement, surveys, experiments).
(Content unavailable)

6.PS.1.c

Determine the factors that will ensure that the data collected is a sample that is representative of a larger population.
(Content unavailable)

6.PS.1.d

Organize and represent data using circle graphs, with and without the use of technology tools. The number of data values should be limited to allow for comparisons that have denominators of 12 or less or those that are factors of 100 (e.g., in a class of 20 students, 7 choose apples as a favorite fruit, so the comparison is 7 out of 20, 7/20, or 35%).

6.PS.1.e

Analyze data represented in a circle graph by making observations and drawing conclusions.
(Content unavailable)

6.PS.1.f

Compare data represented in a circle graph with the same data represented in other graphs, including but not limited to bar graphs, pictographs, and line plots (dot plots), and justify which graphical representation best represents the data.
(Content unavailable)

6.PS.2

The student will represent the mean as a balance point and determine the effect on statistical measures when a data point is added, removed, or changed.

6.PS.2.a

Represent the mean of a set of data graphically as the balance point represented in a line plot (dot plot).
(Content unavailable)

6.PS.2.b

Determine the effect on measures of center when a single value of a data set is added, removed, or changed.
(Content unavailable)

6.PS.2.c

Observe patterns in data to identify outliers and determine their effect on mean, median, mode, or range.
