Dot Plots and Histogram Test

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots representing the frequency of data points. Each dot represents one occurrence of a value.

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into intervals (bins) and the frequency of data points in each interval is represented by the height of bars.

Front

What does 'frequency' mean in statistics?

Back

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

Front

How do you find the mode of a dataset?

Back

The mode is the value that appears most frequently in a dataset.

Front

What is an outlier?

Back

An outlier is a data point that differs significantly from other observations in a dataset, often appearing much higher or lower than the rest.

Front

How can you determine the range of a dataset?

Back

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

Front

What is the purpose of using a dot plot?

Back

Dot plots are used to visualize the distribution of small datasets and to identify patterns, clusters, or outliers.

Front

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

Back

A dot plot displays individual data points, while a histogram groups data into intervals and shows the frequency of data points in each interval.

Front

How do you interpret a histogram?

Back

To interpret a histogram, look at the height of the bars to understand the frequency of data points in each interval and identify the shape of the distribution.

Front

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

Back

A right-skewed histogram indicates that most data points are concentrated on the left side, with a few larger values stretching the tail to the right.
