Data Analysis and Probability Standard for Grades 6-8
| Instructional programs from prekindergarten through grade 12 should enable all students to— |
In grades 6–8 all students should— |
| Formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them |
- formulate questions, design studies, and collect data about a characteristic shared by two populations or different characteristics within one population;
- select, create, and use appropriate graphical representations of data, including histograms, box plots, and scatterplots.
|
| Select and use appropriate statistical methods to analyze data |
- find, use, and interpret measures of center and spread, including mean and interquartile range;
- discuss and understand the correspondence between data sets and their graphical representations, especially histograms, stem-and-leaf plots, box plots, and scatterplots.
|
| Develop and evaluate inferences and predictions that are based on data |
- use observations about differences between two or more samples to make conjectures about the populations from which the samples were taken;
- make conjectures about possible relationships between two characteristics of a sample on the basis of scatterplots of the data and approximate lines of fit;
- use conjectures to formulate new questions and plan new studies to answer them.
|
| Understand and apply basic concepts of probability |
- understand and use appropriate terminology to describe complementary and mutually exclusive events;
- use proportionality and a basic understanding of probability to make and test conjectures about the results of experiments and simulations;
- compute probabilities for simple compound events, using such methods as organized lists, tree diagrams, and area models.
