Exploring Two Way Tables in Lesson 4.3

The video tutorial covers the basics of two-way tables, including their structure and how to interpret them. It explains the concept of relative frequency and how to calculate it using examples. The tutorial also includes practice questions to reinforce understanding and application of two-way tables. Students are encouraged to complete a worksheet and submit it for review.

What is a two-way table?

• A table showing data for one variable

• A statistical table showing observed frequencies for two categories

• A method for calculating averages

• A type of graph for plotting data points

What do the rows in a two-way table represent?

• The total of all categories

• A single category being measured

• One of the two categories being compared

• The grand total of observations

How do you calculate relative frequency from a two-way table?

• Subtract the smallest frequency from the largest

• Multiply the row total by the column total

• Add all the frequencies together

• Divide the category total by the grand total and multiply by 100

What is the grand total of students in the example given?

• 315 students

• 165 students

• 215 students

• 150 students

What percentage of girls are in math class?

• 50%

• 27%

• 33%

• 40%

What is the total percentage when adding up the relative frequencies for math, English, and science?

• 100%

• 90%

• 110%

• 95%

How do you find the percentage of people over 40 against increasing the minimum wage?

• Subtract the number of people for increasing the wage from the total

• Multiply the total frequency by the number of people over 40

• Divide the frequency of people over 40 by 70 and multiply by 100

• Add the frequencies of all age groups and divide by 70

What is the purpose of the worksheet provided in the packet?

• To practice drawing two-way tables

• To calculate grand totals only

• To memorize the definitions

• To practice with two-way tables and understand them better

Where should students submit their completed worksheet?

• On Canvas

• In class

• Directly to the teacher

• On Floop

What additional resource was mentioned for further learning?

• An asynchronous assignment on Canvas

• A textbook chapter

• A YouTube video

• A live webinar
