Intro: Making Inferences and Generalizations Using Data

Real World Connections

How is data used in the real-world to solve problems and make predictions?

Covid-19 and Education

In March 2020, many school systems abruptly closed due to the outbreak and vastly spread Corona Virus. In August, many educational institutes had to make important data driven decisions about the reopening of schools. Take a look...

Poll

Before the reopening of schools in August, Which device(s) did you personally own. This also means not shared.

• Desktop Computer

• Laptop Computer/ Chromebook

• Cell Phone

Using the data...

Discussion: How could data from this question have been useful when deciding to reopen schools in Washington County?

Open Ended

Type one question that the Washington County Board of Education should have or may have asked when making decisions about reopening schools. Make is a statistical question.

Example 1

What possible inferences can we make?

Inferences....

• Most students prefer pizza

  
  

• Tacos and burgers are tied. (Like the same)

  
  

• About six times as many students prefer pizza as those who prefer tacos.

  
  

• More students prefer pizza than those who prefer burgers and tacos combined.

Question 1

Ms. Jennings held a "mystery bag" full of marbles up in front of her class. She said, " There are 100 marbles in this bag. Some are red, and all of the others are blue. I want you to estimate how many red marbles are in the bag without looking in the bag and counting all of them." she then let Joe pick 10 marbles from the bag without looking.

Fill in the Blanks

Suppose Joe had 4 marbles in his sample. Write a ratio representing the number of red marbles in Joe's sample.

Fill in the Blanks

If Joe is not allowed to pull out any more marbles, what do you think his best estimate will be for the total number of red marbles in the mystery bag?
