Using a 2002 California Gray David recall vote as an example, young statisticians  identify sources of bias in samples and find ways of reducing and eliminating sampling bias. They consider ways to select random samples from a...

What is the appropriate model? Sample problems show the extent of the Smarter Balanced assessments Claim 4, Modeling and Data Analysis. Items provide pupils the opportunity to use mathematical modeling to arrive at a reasonable answer....

Young mathematicians define population, draw convenience sample from the population, draw quota sample from the population, and draw random probability sample from the population. They explain why a random probability sample usually...

Over the course of three class periods, middle schoolers design an experiment to provide learner input to administration about which rock band to invite to play at school. They practice several random sampling exercises, all well...

If a random sample determines that 45% of students favor block scheduling, is it possible that the actual percentage might be 50% or 60%? In this task, learners use data from a computer-generated simulation to determine the plausibility...

Students 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...

MAD about statistics? In the seventh chapter of an eight-part seventh-grade workbook series, learners develop probability models and use statistics to draw inferences. In addition, learners play games and conduct experiments to determine...

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 random sample and complete surveys. In this algebra instructional activity, students create surveys and define the way people analyze these results. They discuss random sample as it relates to the Great Depression and...

Students identify the mean and variance. In this statistics lesson, students calculate the population variance using the N as a divisor. They draw the relationship of dividing by N and N-1.

Students test the hypotheses using p values. In this statistics lesson plan, students define and examine conditional probability. They test each statement for a true statement or a false statement, based on the sample size.

Learners examine population growth and collect data. In this statistics lesson, students create a scatter plot to represent the different species found in the water and are being harvested. They graph their data and draw conclusion from it.

How many people do you need in a room before two likely share the same birthday? Scholars consider this puzzle by analyzing a set of data. They ponder how to divide the data and determine the proper size of a group for this event to...

Scholars create and perform experiments attempting to answer Buffon's Coin problem. They discover the relationships between geometry and probability, empirical and theoretical probabilities, and area of a circle and square.

Learners estimate the total number of species in Ecuador using the capture/recapture method. They collect data about each species and act as members of a science expedition to determine the total number of species by using mathematical...

Which fluids make the best bubbles? Pupils experiment with multiple fluids to determine which allows for the largest bubbles before popping. They gather data, analyze it in multiple ways, and answer analysis questions proving they...

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...

There are a number of activities here that look at representing data in different ways. One activity, has young data analysts conduct a class survey regarding a new radio station, summarize a data set, and use central tendencies to...

Upper elementary and middle schoolers work with the concept of probability. They are introduced to the concept of chaos. Learners graph and analyze using a line plot, work with mean, and are introduced to the concept of variance.

Twelfth graders test their knowledge of Algebra II and Trigonometry.  In this Algebra II/Trigonometry lesson, 12th graders are provided with a copy of an Algebra II/Trigonometry Regent Exam from the fall of 2009.  The exam has...

Young scholars identify the probability of an event occurring. Learners explore the complement of an event in finding why an event will not happen. They also explore basics of probability within algebra.

Sixth graders view a Stacked Graph, and discuss what it shows. Students discuss the basics of graphing: labels, intervals, legends x and y axis... Students create individual stacked graphs from provided information. Students view a...

Fourth graders create enlarged replica of a stegosaurus drawing, using a grid to practice coordinates.

Students investigate threee types of maps. In this algebra lesson, students idenitfy different maps and explore how they relate to the area keeping cllimate and topography in mind. They discuss maps used to navigate land. air and sea.
