The instructional activity focuses on the ideas of dot plot representations and the mean absolute deviation of data sets.

Students develop an informal understanding of standard deviation by having students find the mean and standard deviation of their hometown and comparing them to a town with a similar mean but a different standard deviation.

Learners are introduced to the concepts of the normal curve, skewness and the standard deviation. They discuss how the normal distribution has been used and misused to support conclusions.

Scholars research arm span to determine who gives the best bear hugs. They use data from a national study to find the standard statistics for arm span. It includes mean, median, quartiles, spread, standard deviation, and more.

Young scholars collect statistical data.  In groups, students play a dart game and then determine the distance between darts.  They collect the data and plot the information on a coordinate plane.  They identify the mean...

Young mathematicians collect data on the arm spans of classmates. Then they sort the data by measures of center, spread, and standard deviation. Finally, they compare groups, such as boys and girls, to interpret any differences. 

Learners compute the standard deviation for a given set of data. In this measuring dispersion lesson, students compute the mean, and then the distance from the mean for each data point. They find the standard deviation of the data.

High schoolers log their computer usage hours. They determine the mean, median, mode and standard deviation of the collected data. They make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+ graphing...

Learners apply their understanding of luck to a probability experiment. They play a game of Pass the Pigs to determine the probability of a specific outcome. Using analysis for their data, pupils declare the measures of center, dot...

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...

Pupils examine techniques to represent data. For this data analysis lesson, students read about various ways to represent data, such as a stem and leaf diagram and calculating standard deviation. Pupils complete data analysis questions...

Class members study the size of classmates' feet and perform a statistical analysis of their data. They solve for central tendencies, quartiles, and spread for the entire group as well as subgroups. They then write a conclusion based on...

Students identify the standard deviation. In this statistics lesson, students find the mean distribution and calculate the percent of deviation from the mean. They observe this change on the Ti calculator.

Students calculate the standard deviation of data. In this statistics lesson, students collect data, plot it and analyze it. They identify the mean, median and range of their data.

Scholars apply prior knowledge of statistics to write a conclusion. They summarize using correct academic language and tell the story of the data.

students define the alpha level. In this statistics instructional activity, students identify what makes the "null rejected" and discuss the data surrounding the null. They observe the meaning of alpha as it relates to the bell curve.

The news reports on rising sea level, but how do scientists measure this rise? Scholars use NOAA data including maps, apps, and images to work through five levels of activities related to sea level. Each level in the series adds a new...

Students collect and analyze data. In this statistics lesson, students define and calculate the range, median and standard deviation. They identify reasons for a skewed distribution.

Students solve problems by identifying the percent of area under the curve. In this statistics lesson, students discuss z-scores as they calculate the different percentages under the bell curve. They calculate the standard deviation.

Students investigate a particular object then calculate to find the class average and standard deviation.  In this measuring distance lesson students list their calculations on a piece of paper. 

Learners analyze sampling from different population. In this statistics lesson, students define the meaning of sample sizes and what causes an increase or decrease. They graph their data on the Ti calculator and draw conclusion from the...

Students define normal distribution as it relates to the bell curve. In this statistics instructional activity, students use the central tendencies of mean, median and mode to solve problems. They plot their data and draw conclusion from...

Students find different characteristics of the bell curve. In this statistics lesson, students analyze a family for a specific characteristic. They identify the shape, center, spread and area as they analyze the characteristic of the...

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