Investigate the meaning of a sample proportion using this hands-on activity. Scholars collect data and realize that the larger the sample size the more closely the data resembles a normal distribution. They compare the sample proportion...

In this z-score worksheet, students identify the z-scores and percentiles corresponding to thirteen values.  Students are also asked to find two probabilities.  Worked solutions are provided after each question.

In this statistics worksheet, students analyze problems by finding the mean, median and mode. They also set data by their median, and quartiles. There are 7 questions dealing with 2 different sections.

Learners analyze plotted data in this statistics lesson plan. They differentiate between skewed and normal data. They also explore and interconnect exponential growth and decay as it relates to the data.

Students use Internet research to determine the amount of carbon dioxide produced per unit energy for biomass and coal. In this alternative energy lesson, students research to find out how much energy and carbon dioxide several coal and...

Learners participate in an election. They are asked to vote for one of four candidates without knowing who they are or what they stand for. Students gain an important lesson when voting to make sure that security of freedom and...

For this Algebra I worksheet, 9th graders determine the measures of central tendency for a given data set.  The one page worksheet contains four problems.  Answers are provided. 

Students investigate if gender makes a difference in the classroom. For this statistics lesson, students collect data on whether equity by gender in the classroom makes students more successful.

Begin by reviewing mean absolute deviation as a measure of variability. Your new learning will begin with standard deviation and understanding the difference between mean absolute deviation and standard deviation.

Explanation of frequency distributions, mean, standard deviations, and variance including a Java Applet.

This lesson demonstrates to students how to use standard deviation to better understand a set of data. Students use standard deviation to determine the general pattern or shape of a given set of data to draw more reliable conclusions.

This World of Mathematics site by Eric Weisstein explains the term "Standard deviation." Provides step-by-step help, examples, and charts.

Page centered around a computer program to determine mean, variance, and standard deviation.

Students develop a better intuitive understanding of what is meant by variability in statistics. Emphasis is placed on the standard deviation as a measure of variability.

Students learn about mean, median, variance, and standard deviation. The tutorial investigates the statistics concepts though class notes and examples. Review exercises are included.

Provides lengthy explanations of the measures of central tendency - mean, mode, and median - and the measures of variability - range, variance, standard deviation. Graphs of interesting examples are presented as well, skewed...

[Free Registration/Login may be required to access all resource tools.] This Concept teaches students how to find the mean and standard deviation for discrete random variables.

An introduction to recognizing trends and relationships in data through descriptive statistics.

Students will find solutions for a series of questions based on the assumption that SAT mathematics scores for a particular year are approximately normally distributed with a mean of 510 and a standard deviation of 100. Explanation and...

The purpose of this student task is to develop understanding of standard deviation. Aligns with S-ID.A.2 and S-ID.A.3.

This is an excellent resource on what the science of statistics involves. There are all kinds of definitions, examples, graphs, and charts to learn from. The topics covered include: mode, mean, median, skewed distributions and measures...

This is a statistics calculator; enter a data set and hit calculate. Descriptive statistics summarize certain aspects of a data set or a population using numeric calculations. Examples of descriptive statistics include: mean, average,...

The mathematics tutorial investigates statistical studies, central tendency, and dispersion. The lesson consists of class notes, calculator tips, examples, and practice problems with solutions. The teacher resource includes an activity...

In this activity, students compute statistical measures like the mean, standard deviation, and variance of the data set. They understand how measures of variability can be interpreted.
