Water, water, everywhere? Each pupil first uses an Internet program to select 50 random points on Earth to determine the proportion of its surface covered with water. The class then combines data to determine a more accurate estimate.

To understand how biased data is misleading, learners analyze survey data and graphical representations. They use that information to design their own plans to collect information on consumer thoughts about Chocolicious cereal. 

Would you rely on a fortune cookie for advice? The lesson plan first requires future statisticians to categorize 100 fortune cookie fortunes into four types: prophecy, advice, wisdom, and misc. The lesson plan goes on to have learners...

The 19th installment in a 25-part series builds upon the sampling from the previous unit and takes a larger sample. Pupils compare the dot plots of sample means using two different sample sizes to find which one has the better variability.

Are wages based on race? On gender? Class members research wages for workers according to race and gender, create graphs and charts of their data, and compute differences by percentages. They then share their findings with adults and...

How do you find the area of an irregular shape? Class members calculate the area of an irregular shape by finding the area of a random sampling of the shape. Individuals then utilize a confidence interval to improve accuracy and use a...

Pupils work to find probabilities by using areas under the normal curve. Groups work to calculate z-scores and solve real-world problems using the empirical rule or tables.

Using methods adopted by Public Policy Analysts (PPA) class groups define a social problem, gather evidence to document the existence of the problem, identify causes, evaluate existing policies designed to deal with the problem, develop...

How do you summarize data that cannot be averaged? Using an exploratory method, learners complete a two-way frequency table on super powers. The subject matter builds upon 8th grade knowledge of two-way tables. 

Ah, the classic business cycle model: recession, depression, recovery, prosperity. And then there was the Great Depression. Groups investigate the economic conditions that led to and social movements of the 1920s that great out of the...

Introduce line plots, show examples of tables, graphing on a number line, and engage in a class discussion. Share the process by which statistical data is organized and displayed on a number line. Examples and worksheets are included....

More than 90 percent of the people in a building have come down with an illness, and it is your job to investigate. Teachers give scientists the data needed to decide what is important and how they can solve the mystery....

Error does not mean something went wrong! Learners complete a problem from beginning to end using concepts developed throughout the last five lessons. They begin with a set of data, determine a population proportion, analyze their result...

How accurate is data collected from a sample? Learners answer this question using a simulation to model data collected from a sample population. They analyze the data to understand the variability in the results.

Use mathematics and simulations to investigate car crashes. IScholars test hypotheses involving car crashes. They collect, analyze, and display data from computer simulations to support or refute their hypotheses.

Everyone loves a vacation and a set of three activities has groups planning a tour of the U.K. using given distance, time, and price data. They solve a variety of problems related to the trip and produce a report on the success of...

To an engineer, the glass is never half full; it's just double the necessary size. The fifth installment of a nine-part technology and engineering series teaches pupils about the idea of ergonomic design. Measurements of popliteal height...

It's a balancing act! Pupils balance pennies on a ruler to create a physical representation of a dot plot. The scholars then find the distances of the data points from the balance point, the mean.

Scholars investigate the spread of associated data sets by comparing the data sets to determine which has a greater variability. Individuals then interpret the mean as the typical value based upon the variability.

Display data over a larger interval. The fourth segment in a 22-part unit introduces histograms and plotting data within intervals to the class. Pupils create frequency tables with predefined intervals to build histograms. They describe...

Is there a way to measure variability? The ninth resource in a series of 22 introduces mean absolute deviation, a measure of variability. Pupils learn how to determine the measure based upon its name, then they use the mean...

Box in the similarities and differences. The 19th lesson plan in a unit of 22 presents class members with multiple box plots to compare. Learners use their understanding of five-number summaries and box plots to find similarities and...

Take a central look at data. The differentiated lesson plan provides activities for pupils to calculate central tendencies. Scholars begin choosing three central tendency activities from a Tic-Tac-Toe board. Learners then choose from...

An intriguing lesson provides information to help academics understand the role of geography in the diffusion of the COVID-19 illness. Academics interpret charts and make predictions for the future. The timely resource includes...
