Probability Worksheets Grade 8

Probability is a branch of mathematics that involves the study of how likely an event is to occur. Probability worksheets garde 8 help in building a strong foundation in understanding the concept of probability as it is not only used in math but also in real life.

Benefits of 8th Grade Probability Worksheets

The benefit of probability worksheets grade 8 is that students learn how to gauge the probability by tossing a coin, determining the probability from word problems into numbers - odd, even, factors, etc, and the probability of finding a card from a deck of cards. These grade 8 math worksheets provide visual simulations that make it simple and easy for the students to understand the topic better. Since it is a complex topic, the 8th grade probability worksheets provide an answer key with step-by-step solutions in a detailed manner for the students to learn the topic thoroughly and help in improving life and logic skills.

Probability tells us how often some event will happen after many repeated trials. You've experienced probability when you've flipped a coin, rolled some dice, or looked at a weather forecast. Go deeper with your understanding of probability as you learn about theoretical, experimental, and compound probability, and investigate permutations, combinations, and more!

What Do You Mean by Statistics?

What are the applications of statistics.

Among the applications of statistics is when a statistician collects information. A sample of the population is used. The individual typically cannot survey everyone in a group or study them because the numbers are simply too big. The sample is nothing more than a portion of the population that is believed to be representative of the entire group.

To determine the average weight of adult Americans, the statistician would survey a few thousand adults. If the sample accurately reflects the population, the average height determined by the results would be very close to the average height of adult Americans as a whole group.

What Are Examples of Statistics?

How does a person go about collecting these stats? Examples of statistics can include a variety of methods. The method selected depends on the question being asked by the statistician and the statistical information to be collected. Simple random samples are one option, but a person might find he or she benefits more from a cluster or stratified sample.

Regardless of which method is selected, the statistician must share this information with others so they can replicate the study if desired. Each type of sample has its benefits and drawbacks, which need to be considered before the data collection process begins.

A Statistics Worksheet Can Help Organize Data

As data is collected, it must be organized to ensure information can be pulled from it. A statistics worksheet offered by Cazoom Maths can help students learn how to gather and organize the data. With these worksheets, students can spot trends and patterns.

When comparing stats worksheets, students must decide if they will benefit most from a worksheet with a pie chart, one that creates a circle graph, or if another option should be selected. Other choices include stem-and-leaf plots, scatterplots, bar graphs, box-and-whisker graphs, and time plots.

Researchers Use Descriptive Statistics to Calculate Quantities

Inferential statistics is based on hypothesis testing.

Hypothesis testing is a major part of inferential statistics. Researchers start with a sample and use the material gathered to try to infer something about the overall population. A hypothesis is formed before researchers use statistical tools to decide whether to accept or reject the theory.

Why Are Statistics Important?

Statistics are important because almost every scientific research field uses statistics in one way or another. Advertising is a good example, while psychologists use statistics to learn more about a patient with relation to the general population. Economics is another field that relies on statistics and the same is true of medicine along with many other areas.

Statistics is a difficult subject for many students. They struggle to determine the probability of an event or whether an occurrence is random. Fortunately, with the help of statistics worksheets offered by Cazoom Maths, the entire process becomes clearer.

Be aware that, as Mark Twain pointed out, the person using the data determines in part how it is shared because statistics are pliable. For this reason, worksheets are of great help. They can teach a student to see trends and patterns before any analysis is conducted.

Lesson 1 – Review of Probability

Time Estimate: one 50 minute period

This is meant to be a "teacher led" lesson, best carried out with a computer with internet access and an LCD projector. Teacher will show a BrainPop movie and Interactive quiz called Basic Probability – currently offered as a free sample on this web site. Then the teacher will open a review of Probability Review web site at Math Goodies to discuss previous student learning

Lesson 2 – Internet Interactive Student Activities

Time Estimate: two 50 minute periods

These two activities should be completed by students in a computer lab setting. If possible, students can work independently at one computer or if need be with a partner sharing a computer. Prior to the class, the teacher should print and copy a student worksheet for each student. The student should complete the sheet and keep it as an artifact to assist them in their mini-unit assignment.

Alternatively, the teacher can lead students through both activities as a class using a computer and LCD projector. In this case, students should each have their own worksheet to complete as the teacher goes through the activity.

Lesson 3 – Rock, Paper, Scissors

Time Estimate: three 50 minute periods

This lesson begins in the classroom with students working with a partner playing 25 games of Rock, Paper, Scissors. Students should each have the activity worksheet or alternatively, an overhead transparency could guide students through the class activity.

Class data should be recorded on the whiteboard and acts to increase the number of trials for the activity.

Students will complete a worksheet (included) on the possible outcomes of the two player game and then work on a computer to produce a spreadsheet and pie graph of their class data.

Lesson 4 – Probability Assignment: Concept Map

Time Estimate: one to three 50 minute periods

In this assignment students will demonstrate their understanding of experimental and theoretical probability by producing a concept map using Inspiration software. Again, students are ideally working independently on a computer or with a partner sharing a computer.

Depending on their experience with the program, teachers may wish to spend a period examining the software.

Students will complete the following:

and will produce:
