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...

Pupils 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 data.

Sixth graders explore the concept of biodiversity.  In this biodiversity lesson, 6th graders discover a variety of planets and animals that live in forests, and how a rotting log benefits that environment.  Students also locate...

If a random sample determines that 45% of learners 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 create an insect out of food.  In this insect characteristics lesson, students review the 3 body parts of an insect and use various foods to create a sample insect.  Students learn a song about insect body parts.

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...

Students define random sample and complete surveys. In this algebra lesson, students create surveys and define the way people analyze these results. They discuss random sample as it relates to the Great Depression and come up with their...

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.

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, students define and examine conditional probability. They test each statement for a true statement or a false statement, based on the sample size.

Students 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.

Students create a resume for themselves using a Microsoft Word template. Students view and evaluate sample resumes and complete a worksheet to determine the information they should include in the resume they complete for themselves.

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

Your youngsters will be experts on the geography of Australia after working with these activities and worksheets, which review the continent's weather, major landforms, dimensions, history, and climate.

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...

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...

After a class discussion where kids share how they find answers to their questions, learners explore the world of reference materials such as, an atlas, an almanac, and an encyclopedia. The Internet is also discussed as a way to access...

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...
