| The
Algebra Utah Core objectives for statistics focus
primarily on scatter plots and line of best fit. For
purposes of contrast, other statistical concepts are
included below.
*Alg Stats 2.1 covers stem and leaf and box plots
and measures of central tendency .
*Alg Stats 2.2 covers the same as 2.1, but involves
comparing more than one set of data.
*Alg Stats 2.3 and 2.4 involves two variable data,
introduces scatter plots and line of best fit.
*Alg Stats 2.5 and 2.6 involve all of the concepts
included above.
*Some lessons below can be accessed from NCTM's Navigating

Lesson
Summary
|
|
| Alg
Stats 2.1a Pulse Rates
PDF
|
Students
collect data for resting, exercising and recovery
pulse rates, organize the data into stem and leaf
plots, use the calculator to create histograms and
box plots, sketch the graphs and record and analyze
the statistics.
|
Alg
Stats 2.1b Central Tendency Questions PDF
|
Students
answer questions geared to help them differentiate different
measures of central tendency. |
Alg
Stats 2.2a NBA Heights
PDF
|
Students
use stem and leaf plots, histograms and box plots to
examine how much taller NBA basketball players are than
students? |
Alg
Stats 2.2b Testing Batteries
PDF
|
Students
consider the question of how to determine which brand
of batteries is better, examine and organize data, create
plots, analyze the results in order to respond to the
battery question. |
Alg
Stats 2.2c Stopping Distances
PDF
|
Students
consider the question of how much distance cars need
for stopping at different speeds and whether or not
different kinds of cars stop faster than others? They
examine and organize data, create plots and analyze
their results |
Alg
Stats 2.2d Reaction Times
PDF
|
Students
consider the question of different reaction times for
different people, collect reaction time data, organize
small and large data samplings, create histograms, examine
a normal curve representation for a general population.
|
| *To
correlate the study of statistical scatter plots and
"line of best fit" with the conceptual foundation
for linear equations, please refer to Module 4, lessons
4.6 to 4.8. |
Alg
Stats 2.3a Scatter Plots
PDF
|
Students
examine a scatter plot relating area codes and state
population and are introduced to the concept of a line
of best fit. |
| Alg
Stats 2.3b Line of Best Fit Contest
PDF
|
Students
create graphs by hand and on the calculator. They use
string, spaghetti, and a toothpick to determine a line
of best fit, create an equation. Then they have the
calculator create the linear regression to see who won
the contest. |
Alg
Stats 2.4 Head Hunters
PDF
|
Students
create a scatter plot and line of best fit to examine
the relationship of head circumference to height. |
| Alg
Stats 2.5 Predictions |
Students
create scatter plots to study correlations in Olympic
times and decades, population growth in the U.S., factors
in financial success of movies. (Please

grades 6-8 ) |
| *Dave
Bradley's Data Activities for Pre-Algebra(includes internet
statistics links) |
Students
will pick a statistical question of their own, research
data and answer the question using statistical measures.
*Access Dave Bradley's links at left. |
| Alg
Stats 2.6 Congress and Pizza |
Students
examine the question of whether or not we can predict
how many pizza restaurants there are in a state based
on how many congressmen there are and whether or not
? (Please access pp.102-103, Navigating Through Data
