Just how confident can we be with statistics calculated from a sample? Learners take this into account as they look at data from a sample of petroleum engineer salaries. They analyze the effect sample size has on a margin of error and...

In this confidence interval worksheet, students examine a given confidence level and sample data to determine the margin of error, identify a confidence interval, list the mean and give the standard deviation. Students complete seven...

In this confidence interval worksheet, students examine given statistical information to find the margin of error. They construct a confidence interval for the population and find the mean. Seven statistical problems are available on...

In this interval worksheet, young scholars examine given data to construct a confidence interval for a specified proportion. They also identify the minimum sample size needed to support the required margin of error around the population....

For this two-sided confidence interval worksheet, students solve 3 problems to include constructing a confidence interval for a population proportion with a large sample. First, they split the confidence and shad its cumulative are for a...

How confident are you? Explore the meaning of a confidence interval using class collected data. Learners analyze data and follow the steps to determine a 95 percent confidence interval. They then interpret the meaning of the confidence...

Making inferences isn't an exact science. Using data about salaries, learners investigate the accuracy of their inferences. Their analyses includes simulations and randomization tests as well as population means.

Pupils collect data and graph it. In this statistics instructional activity, students rate confidence levels by collecting data and analyzing it. They graph their findings on the Ti calculator.

Decimals are quite often confusing for young mathematicians. Pupils engage in three activities: writing decimal names, understanding place value, and comparing decimals to thousandths. At the end of the lesson, there is a motivating game...

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...

There are places in the US where a road cannot be found for miles! The lesson asks learners to use random longitude and latitude coordinates within the US to collect data. They then determine the sample proportion and confidence interval...

One of the key questions in statistics is whether the results are good enough. Use an activity to help pupils understand the importance of sample size and the effect it has on variability. Groups collect their own sample data and compare...

Most adults dread April 15 — tax day! Tax preparation can be intimidating even for adults. Build confidence by leading individuals through the process and then give them a scenario to practice. The exercise uses tax vocabulary to give...

In this random samples activity, students answer 4 questions, including a bonus, regarding surveys and confidence intervals.

Students define sample, describe a random sample, and discuss what compromises a sample. They determine a sample size to estimate a population characteristic with confidence.

Build on your learners' confidence in quick addition as they discover strategies to add tens to two-digit numbers. After reviewing counting by 10's, they discuss tactics to add multiples of 10 to other numbers. They visualize how to...

Factoring numbers helps prepare scholars for fractions and algebra, so build confidence by drilling this skill and promoting reflection in the process. Scholars start by listing factors for 18 numbers, none of which exceed 30. Next, they...

Encourage number confidence by focusing on one number at a time; young counters examine the number seven, starting by tracing the numeral three times and printing a few more on their own. Next, they count three sets of flowers in an...

As scholars become more confident with their multiplication facts, give them some two-digit practice problems to solidify their skills. They solve 30 vertically-aligned problems, regrouping where necessary. All of these have one 2-digit...
