Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

Reduce variability for more accurate statistics. Through simulation, learners examine sample data and calculate a sample mean. They understand that increasing the number of samples creates results that are more representative of the...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Calculators sure come in handy. An AP® Statistics instructional resource provides suggestions for using calculator simulations. It gives activities for adding variances, normal probability plots, and t distributions.

Explore the concept of mean, median, and mode with pupils. They estimate the length of a string or the number of M&M's in a jar. Then find the mean, median, and mode of the class' estimates.

Don't assume your pupils understand assumptions. A teacher resource provides valuable information on inferences, assumptions, and conditions, and how scholars tend to overlook these aspects. It focuses on regression analysis, statistical...

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.

Students examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. They practice science and math in real world applications. They write reports detailing their scientific...

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 make sequential patterns by using ants and following the model. They identify different parts of an ant by matching the picture to the word name. Pupils identify the ant's life cycle by creating a chart using pictures.

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.

Students explore and analyze atmospheric conditions for a high mountain retreat. They examine the relationship between altitude, atmospheric pressure, temperature and humidity at a particular location. In addition, they write reports...

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

How to find the standard deviation is explained and demonstrated with this calculator. Reloading the page presents you with new numbers.

Gain an understanding of standard deviation and normal distribution by viewing an example and a video lesson.

Calculate the standard deviation of a population. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

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

Standard devaition and variance are explained clearly, accompanied by an examples using the size of dogs.

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

Very complete explanation of mean, standard deviation, etc. including an online calcluator for these statistics.

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.
