Measurement and Data

What is the purpose of comparing two groups of numeric data using comparative dot plots or box plots?

• To compare their shapes, centers, and spreads

• To calculate the sum of the data

• To find the highest value in each group

• To determine which group has more data points

How can data from a random sample be used?

• To calculate the area of a circle

• To predict the weather

• To write a story

• To make inferences about a population

What is compared when analyzing two populations based on data in random samples?

• Informal comparative inferences about differences between the two populations

• The number of samples taken

• The color of the data points

• The names of the populations

What mathematical process is applied to use statistical representations to analyze data?

• Algebraic thinking

• Fraction operations

• Measurement and data

• Geometry

What can be learned by comparing box plots?

• How to compare by using their shape, spread, and center

• How to draw a perfect circle

• The exact number of data points

• How to multiply the data points

What is the goal of making inferences about larger populations from random samples?

• To guess the population's favorite color

• To count every individual in the population

• To ignore the sample data

• To understand characteristics of the whole population

Why compare two populations represented on the same graph?

• To make inferences about the larger population

• To decide which graph is prettier

• To practice drawing graphs

• To find out which population is older
