What are the two types of questions a Pie chart can never answer?

Who and Why

100
  1. What does each picture represent if 1 picture = 3 books?

Each picture represents the number of books. So one picture is 3 books. 

100
  1. Organize these numbers into a stem-and-leaf plot: 12, 15, 22, 24, 25.

the stem should only have 1 and 2. The leaves should have 5 numbers in total.

200
  1. Subtract −5 from 8.

13

  1. Find ∣5−12∣

7

200
  1. Plot these numbers on a dot plot: 2, 3, 3, 4, 5.

one dot on 2, two dots on 3, one dot on 4, and one dot on 5. 

200

One picture represents 2 books. How many books are shown if 4 pictures are displayed?

8 books

200
  1. Create a stem-and-leaf plot for these numbers: 31, 33, 35, 37, 39.

Teacher will check.

  1. Multiply −3×4

-12

  1. Find ∣-7|

300
  1. Create a dot plot with these values: 1, 1, 2, 3, 3, 3, 4.

two dots on 1, one dot on 2, three dots on 3 and one dot on 4. 

300
  1. If a pictograph has 5 pictures representing 2 students each, how many students are there?

10 students

300

What do line graphs measure?

The growth or decline of something over time. Growth/decline over time. growth and time. time time time and time. Line graphs ALWAYS deal with TIME.  

400
  1. Divide −24÷6

-4

400
  1. Compare ∣−3∣ and ∣3∣. Which is greater?

they are equal

If I wanted to create a pie chart about people's favorite foods, what method of data collection would I need to use?

Survey

400
  1. Create a bar graph from this data: A=3, B=5, C=2.

Lines on the y axis should mark up to five at least. The x axis should have labels A, B, and C. The bar on A should go up to 3, B should go all the way to five, and C should go to 2. 

400

What is the main thing you can compare on a pie chart?

you can compare the individual parts to the whole. In other words, if we sample people's preferred sports, we can compare how many people like soccer to the whole group of people we sampled to see if its a lot of people that like soccer or a few people.

  1. Order the integers −3,7,−1,0 from least to greatest.

-3, -1, 0, 7

500

How many numbers are in-between -4 and 3?

6 (-3, -2, -1, 0, 1, 2)

If I want to get a sample size that is representative of the population of Norview Middle School, how should I select my sample?

I need to select randomly. Random sample yields a greater scope of generalization. 

500

What is the difference between a bar graph and a pictograph?

1. Pictographs have pictures, bar graphs have bars.

2. Pictographs require keys, bar graphs do not need keys to be understood.
