3.2 Data, Statistics, and Probability Performance Indicators
a. represents, analyzes, and solves problems with data presented in various forms
(e.g., line plots, bar graphs, picture graphs)
b. demonstrates knowledge of statistical variability and measures and summarizes
and describes data distributions (e.g., number lines, dot plots, histograms, box
plots)
c. demonstrates knowledge of the use of random sampling to draw inferences about
a population and identifies sources of bias in sampling methods
d. draws informal or comparative inferences about two populations using data
distributions and measures of center (e.g., mean, median) and variability (e.g.,
interquartile range, mean absolute deviation, standard deviation)
e. investigates chance processes and develops, uses, and evaluates probability
models (e.g., independent and dependent events)
f. investigates patterns of association in bivariate data using scatter plots, linear
models, and two-way tables
d. uses measures of center (e.g., mean, median) and range to describe patterns in a
data set and to identify outliers

3.2 is Data, Statistics, and Probability. This sub-section has several indicators
no longer tested in Mathematics 246. It also has addition of Performance
Indicators unique to Mathematics 246.
Performance Indicator “b” has a partial elimination. This Performance
Indicator states that it demonstrates knowledge of statistical variability and
measures and summarizes and describes data distributions. It is under the
examples where there is a change in this Performance Indicator. “Box plots” is
no longer tested as that concept is introduced in grade seven.
P
erformance Indicator “c” indicates a partial removal as well as an addition.
This
Performance Indicator demonstrates knowledge of the use of random
sampling and (this is new) identifies sources of bias in sampling methods, no
longer to “draw inferences about a population.”
Performance Indicators from Mathematics 212 “d” through “f” are no longer
tested in Mathematics 246.
There is a new “d” for this subsection; this Performance Indicator uses
measures of center (e.g., mean, median) and range to describe patterns in a
data set and to identify outliers. Please review these carefully.
