What is a frequency polygon?

• A type of graph that shows the relationship between two variables.

• A line graph that connects the midpoints of the top of the bars in a histogram

• A chart that lists all the data points in a table

• A circle graph that shows percentages.
  

In a frequency polygon, what does the x-axis usually represent?

• The frequency of the data.

• The categories or intervals of the data

• The total number of data points.

• The average of the data.

How do you create a frequency polygon from a histogram?

• By drawing a bar for each category.

• By connecting the midpoints of the top of the bars with straight lines.

• By adding more data points.

• By calculating the mean of the data.
  

If a frequency polygon has a peak, what does that indicate?

• There are no data points in that category

• That category has the highest frequency.

• The data is evenly distributed.

• The data is decreasing.

Which of the following is NOT a benefit of using a frequency polygon?

• It shows trends in data over time

• It makes it easy to compare different sets of data.

• It can display individual data points clearly.

• It helps visualize the shape of the data distribution.

What is the main purpose of a frequency polygon?

• To show the average of a set of data

• To display how many times each value occurs in a dataset.

• To list all the data points in a table.

• To compare two different datasets

When drawing a frequency polygon, what should you do with the last data point?

• Leave it out.

• Connect it to the x-axis.

• Make it a different color.

• Write a label next to it.

Which of the following is a characteristic of a frequency polygon?

• It uses bars to represent data.

• It is always a straight line.

• It can show trends over time.

• It only displays one data point.

If the frequency polygon is rising, what does that indicate about the data?

• The data is decreasing.

• The data is constant.

• The data is increasing.

• There is no data.

Which of the following can be used to create a frequency polygon?

• A pie chart.

• A histogram.

• A scatter plot.

• A line graph.
