What does it mean to be normal in the world of statistics? Pupils first explore the meaning of a normal distribution in the eight-lesson module. They then apply the statistics related to normal distributions such as mean, standard...

Your learners will practice many ways of describing data using coordinate algebra in this unit written to address many Common Core State Standards. Simple examples of different ways to organize data are shared and then practice problems...

All disciplines use data! A seven-lesson unit teaches learners the basics of analyzing all types of data. The unit begins with a study of the shape of data displays and the analysis of a normal distribution. Later lessons discuss the...

Understanding the importance of SAT scores is as easy as ABC. A set of three statistics lessons teaches scholars about normal distributions, the Empirical Rule, and z-scores. They apply their newfound knowledge to investigate data...

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.

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

A demonstration of how to find the standard deviation of a set of data. Several examples and a practice test are offered.

An online course on the fundamentals of statistics including video lessons in Mean, Median, and Mode; Weighted Averages; Quartiles and Boxplots; Range and Standard Deviation; Normal Distribution; Z-scores; Intro to Inferential...

Video presentation on the probability of independent events, covering related topics: multiplication rule, random variable, and mean and standard deviation. [28:41]

This site looks at measures of central tendency and dispersion. Discussed are topics such as standard deviation, mean, median, and mode.

[Free Registration/Login may be required to access all resource tools.] Understanding the mean and statistical deviations.

A tutorial to understand the three central tendencies and how to find them, as well as the standard deviation of values. Offers a discussion and practice problems.

[Free Registration/Login may be required to access all resource tools.] Introduces students to the Central Limit Theorem. Students will learn about the Central Limit Theorem and calculate a sampling distribution using the mean and...

Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.
