Lesson 5 Comparing Dot Plots

Front

What is a dot plot?

Back

A dot plot is a statistical chart that consists of dots representing the frequency of data points in a dataset.

Front

What does 'spread of the data' refer to?

Back

The spread of the data refers to how far apart the data points are from each other, indicating the variability in the 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 the median of a dataset?

Back

The median is the middle value when the data points are arranged in ascending order.

Front

What does it mean for a dot plot to be 'skewed right'?

Back

A dot plot is skewed right if the tail on the right side of the distribution is longer or fatter than the left side.

Front

What does it mean for a dot plot to be 'skewed left'?

Back

A dot plot is skewed left if the tail on the left side of the distribution is longer or fatter than the right side.

Front

What is a symmetrical dot plot?

Back

A symmetrical dot plot has a balanced shape, where the left and right sides are mirror images of each other.

Front

How do you determine if dot plots are symmetric?

Back

Dot plots are symmetric if they have the same shape on both sides of the center point.

Front

What is the range of a dataset?

Back

The range is the difference between the highest and lowest values in a dataset.

Front

What is the significance of the mode in data analysis?

Back

The mode helps identify the most common value in a dataset, which can be useful for understanding trends.
