What is a Dot Plot?

Back

A dot plot is a statistical chart that uses dots to represent the frequency of data points in a dataset. Each dot represents one occurrence of a value.

How do you find the Mode in a dataset?

Back

The mode is the value that appears most frequently in a dataset. To find it, count how many times each value occurs and identify the one with the highest count.

Front

What is an Outlier?

Back

An outlier is a data point that differs significantly from other observations in a dataset. It can be much higher or lower than the rest of the data.

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.

Front

What does it mean if a dataset has no Mode?

Back

If a dataset has no mode, it means that no number repeats; all values occur with the same frequency.

What is the purpose of a Dot Plot?

Back

Dot plots are used to visualize the distribution of data points, making it easy to see patterns, clusters, and outliers.

Front

How can you identify the Mode from a Dot Plot?

Back

In a dot plot, the mode is represented by the column with the most dots stacked on top of each other.

Front

What is the difference between Mode and Median?

Back

The mode is the most frequently occurring value, while the median is the middle value when the data is arranged in order.

Front

What is a frequency distribution?

Back

A frequency distribution is a summary of how often each value occurs in a dataset, often represented in a table or graph.

Front

How do you represent data in a Dot Plot?

Back

To create a dot plot, draw a number line and place a dot above the corresponding value for each occurrence of that value.
