Means With Confidence
Students estimate the true mean of a population when the standard deviation is known by finding the sample mean, margin of error and confidence interval.https://education.ti.com/en/activity/detail/means-with-confidence
What Is Your Grade (Part 2)
In this activity, students use the CellSheet Application to determine the missing value in a weighted mean. They use the application to write a formula to find the weighted mean and also learn to use the copy and paste features.https://education.ti.com/en/activity/detail/what-is-your-grade-part-2
NUMB3RS - Season 3 - "Contenders" - Choosing Contenders
In "Contenders," the FBI asks Charlie and Amita to look at official league rankings of each fighter and compare them with their own 'rankings,' created using the skill levels and past performances of each fighter. They find that one fighter has had an easy path to the championship because this fi...https://education.ti.com/en/activity/detail/numb3rs--season-3--contenders--choosing-contenders
What Is Your Grade (Part 1)
In this activity, students will use the CellSheet Application and set up a spreadsheet. They will determine the mean of a set of values and find a minimum value to be added to a set of values to obtain a given mean.https://education.ti.com/en/activity/detail/what-is-your-grade-part-1
Testing Hypotheses (Means, Proportions, and Standard Deviations)
In this activity, students evaluate hypotheses.https://education.ti.com/en/activity/detail/testing-hypotheses-means-proportions-and-standard-deviations
What is Linear Regression?
In this activity, students will explore finding the line of best fit based on the sum of the squares of the residuals and determine what the linear regression line is.https://education.ti.com/en/activity/detail/what-is-linear-regression
NUMB3RS - Season 2 - "Toxin" - How Hard Can It Be?
In "Toxin," the FBI tracks a serial poisoner who uses contaminated drugs. In this activity, the FBI intercepted an encrypted message they believe contains a phone number that could lead to an "insider" who may be helping the poisoner. Don suggests using a computer to start trying to break the cod...https://education.ti.com/en/activity/detail/numb3rs--season-2--toxin--how-hard-can-it-be
