Probability and Random Variables

A probability distribution describes the range of possible values a random variable can have. In the activities in this unit, students investigate discrete and continuous distributions, explore the Law of Large Numbers, examine two-way tables and use simulation to estimate solutions to probability problems. They also focus on probability concepts such as conditional probability, independence and dependence and mutually exclusive events.

Statistics: Probability and Random Variables Activities

Title
Two-way Tables and Association This lesson involves analyzing the results of a survey using a two-way frequency table. Standards \| Textbook	3260	13
Probability Distributions Students will describe how the distribution of a random sample of outcomes provides information about the actual distribution of outcomes in a discrete sample space. Then they will identify the structure that emerges as more and more data are added to a distribution (that is, the features of the distribution of random processes stabilize as the sample gets larger). Students will recognize that relative frequencies of particular outcomes after a few observations are more likely to deviate substantially from exact values than are relative frequencies based on more observations.

Tossing Dice This lesson involves simulating tossing two fair dice, recording the sum of the faces, and creating a dotplot of the sums. Standards \| Textbook	3256	12
Tossing Coins In this activity, students will use a simulation to find the experimental probability of independent events, tossing two coins. They will find the sample space and then compare the experimental and theoretical probabilities. Standards \| Textbook	2964	3
Binomial Pdf- Eye Color This lesson involves binomial trials, distributions, and probabilities. Students can create the tns file following the steps in Binomial_Pdf_Create_Eye_Color, or they can use the premade file Binomial_Pdf_Eye_Color.tns Standards \| Textbook	3279	16
Why np Min? This lesson involves examining the general shape of binomial distributions for a variety of values of n and p. Standards \| Textbook	3759	13
Conditional Probability This lesson involves thinking about probability when additional information is given. Standards \| Textbook	3321	13
