Sophia: Sample and Population: Lesson 1

Increase your sample and increase your accuracy! Scholars complete an activity that compares sample size to variability in results. Learners realize that the greater the sample size, the smaller the range in the distribution of sample...

Reduce variability for more accurate statistics. Through simulation, learners examine sample data and calculate a sample mean. They understand that increasing the number of samples creates results that are more representative of the...

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.

Don't leave your classes vulnerable in their calculations! Help them understand the importance of calculating a margin of error to represent the variability in their sample mean. 

This lesson demonstrates how to subtract vector components. It is 1 of 2 in the series titled "Subtracting Vector Components." [10:32]

From this lesson, you will discover how to make an equation easier to solve by applying simplifying rules to equations. It is 1 of 12 in the series titled "Simplifying an Equation."

Discover the difference between a sample and a population and how they are used in surveys. Assess learning with a quiz. [2:26]

Students compare contemporary cultural differences with historical differences based on population percentage. In this cross-curriculum Gold Rush/math activity, students analyze aspects of California's Gold Rush population and diversity...

This lesson introduces the concept of sampling with and without replacement and how it affects probability. It is 1 of 4 in the series titled "Sampling and Replacement."

This lesson introduces and defines the terms sample and population.
