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
|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
- select, create, and use appropriate graphical representations of data,
including histograms, box plots, and scatterplots.
|Select and use appropriate statistical methods to analyze
- find, use, and interpret measures of center and spread, including mean and
- 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
- use conjectures to formulate new questions and plan new studies to answer
|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
