Stage 1 - Desired Results
DATA AND STATISTICS – UNIT ONE
Standards:                                                                                                 CS
M7D1. Students will pose questions, collect data, represent and analyze the data, and interpret results.
M7A3. Students will understand relationships between two variables.
Standard Elements
**Formulate questions and collect data from a census of at least 30 objects and from samples of varying
sizes.
** Construct frequency distributions
**Analyze data using measures of central tendency (mean, median, and mode), including recognition of
outliers.
**Analyze data using appropriate graphs, including pictographs, histograms, bar graphs, line graphs, circle
graphs, and line plots, box and whiskers plot and scatter plots, some of which may be prior knowledge from
**Analyze data with respect to measures of variation (range, quartiles, interquartile range).
**Analyze and draw conclusions about data, including a description of the relationship between two
variables.
**Plot points on a coordinate plane
**Describe how change in one variable affects the other variable.

What type of relationship can be formed from
 Students will understand how to use graphs to two sets of data?
show a relationship between two sets of data.
What is meant by the center of the data set,
how is it found and how is it useful when
analyzing data

In what ways are sample statistics related to the
corresponding population parameters?

What conclusions can be drawn from data?
Students will know…                                  Students will be able to…

1) compute the measures of central
1.) measures of Central Tendency of a set of            tendency: mean, median, mode &
data.                                               outliers

2.) measures of Variation: range, interquartile      2) compute the measures of variation:
range, lower quartile and upper quartile            range, interquartile range, upper and
lower quartile

3.) elements of the coordinate plane                 3) analyze appropriate graphs.
4.) types of graphs : bar graphs, line graphs,
stem and leaf plots, scatter plots, box and      4) create a box and whiskers plot using
whisker plot, and line plots                        measures of variation.

5) draw conclusions and distinguish a
correlation between two sets of data.

6) plot points on a coordinate plane.

7) create a scatterplot

8) create a stem and leaf plot
