Exploring Frequency Tables, Dot Plots, and Histograms

What is the primary purpose of a frequency table?

• To plot data on a graph

• To calculate the mean of a dataset

• To organize data for easy analysis

• To determine the range of a dataset

Which color was the mode in the favorite color frequency table?

• Green

• Red

• Yellow

• Blue

Why can't you use a frequency table of colors to find the median?

• Colors cannot be organized in ascending order

• The table only shows modes

• Colors are not numerical data

• The median requires interval data

What is the significance of using intervals in frequency tables?

• It simplifies data of a wide range

• It is required for finding the mode

• It is only used for color data

• It helps in finding the exact value of data points

How are ages grouped in the frequency table example?

• In groups of 5 years

• In groups of 10 years

• By individual ages

• In random intervals

What distinguishes a histogram from a bar graph?

• Histograms only display numerical data

• Histograms use intervals on the x-axis

• Histograms cannot show frequencies

• Histograms have gaps between bars

Why are there no gaps between bars in a histogram?

• Because it's a requirement of all graphs

• To indicate continuous data

• To save space on the graph

• To make the graph easier to read

What tool is recommended for drawing straight lines in a histogram?

• A ruler

• A compass

• Freehand drawing

• A protractor

Why might graph paper be helpful when creating a histogram?

• It is required for histograms

• It makes the histogram colorful

• It helps in drawing accurate intervals

• It provides a range of colors

In the age range histogram, which age group was represented by a bar reaching up to 5?

• 40 to 49

• 50 to 59

• 30 to 39

• 20 to 29
