Dot Plots and Histograms Flashcard

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots plotted on a number line, where each dot represents a data point.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, using bars to show the frequency of data points within specified intervals.

Front

How do you find the range of a data set?

Back

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

Front

What does each dot represent in a dot plot?

Back

Each dot in a dot plot typically represents one individual data point or observation.

Front

How do you determine the frequency of a specific interval in a histogram?

Back

The frequency of a specific interval is determined by counting the number of data points that fall within that interval.

Front

What is the purpose of using a dot plot?

Back

Dot plots are used to visualize the distribution of small data sets and to identify patterns or trends.

Front

What is the purpose of using a histogram?

Back

Histograms are used to visualize the distribution of larger data sets and to understand the frequency of data points across different intervals.

Front

How can you tell which interval has the most data points in a histogram?

Back

The interval with the tallest bar in the histogram represents the interval with the most data points.

Front

What does it mean if a dot plot has a cluster of dots?

Back

A cluster of dots in a dot plot indicates that many data points have similar values.

Front

What is an outlier in a data set?

Back

An outlier is a data point that is significantly different from the other data points in the set.
