Dot Plots & Frequency Tables (4.9A)

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted above a number line, where each dot represents a data point. It is used to visualize the distribution of data.

Front

How do you create a frequency table?

Back

To create a frequency table, list all unique data values in one column and count how many times each value occurs in the dataset, placing these counts in the adjacent column.

Front

What does the term 'frequency' refer to in statistics?

Back

Frequency refers to the number of times a particular value or category occurs in a dataset.

Front

How can you determine the mode from a dot plot?

Back

The mode is the value that appears most frequently in the dataset, which can be identified by the highest stack of dots in a dot plot.

Front

What is the purpose of using a frequency table?

Back

A frequency table organizes data to show how often each value occurs, making it easier to analyze and interpret the data.

Front

How do you interpret a dot plot?

Back

To interpret a dot plot, observe the number of dots above each value to understand the distribution, frequency, and any patterns in the data.

Front

What is the difference between a dot plot and a bar graph?

Back

A dot plot displays individual data points as dots, while a bar graph uses bars to represent the frequency of categories, making it easier to compare different groups.

Front

How can you find the total number of data points represented in a dot plot?

Back

To find the total number of data points in a dot plot, count all the dots plotted above the number line.

Front

What is the significance of the highest point in a frequency table?

Back

The highest point in a frequency table indicates the mode, or the most frequently occurring value in the dataset.

Front

How do you calculate the range of a dataset?

Back

The range is calculated by subtracting the smallest value from the largest value in the dataset.
