Dot plots and histograms

Front

What is a dot plot?

Back

A dot plot is a simple visual representation of data using dots to show the frequency of values. Each dot represents one occurrence of a value.

Front

What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within certain ranges (bins).

Front

What does the peak of a data set represent?

Back

The peak of a data set represents the mode, which is the value that appears most frequently.

Front

How do you find the range of a data set?

Back

The range is found by subtracting the smallest value from the largest value in the data set.

Front

What is the mode of a data set?

Back

The mode is the number that appears most often in a data set.

Front

How can you determine the frequency of a value in a dot plot?

Back

The frequency of a value in a dot plot is determined by counting the number of dots above that value.

Front

What is the difference between a dot plot and a histogram?

Back

A dot plot shows individual data points with dots, while a histogram groups data into ranges and uses bars to show frequency.

Front

What does it mean if a histogram is skewed to the right?

Back

If a histogram is skewed to the right, it means that most of the data points are concentrated on the left side, with fewer high values.

Front

How do you interpret the height of bars in a histogram?

Back

The height of the bars in a histogram represents the frequency of data points within each range (bin).

Front

What is a data set?

Back

A data set is a collection of related values or observations that can be analyzed.
