Data Distribution

Front

What is data distribution?

Back

Data distribution refers to how values of a dataset are spread or arranged. It shows the frequency of each value or range of values.

Front

What does it mean if data is skewed right?

Back

If data is skewed right, it means that the tail on the right side of the distribution is longer or fatter than the left side, indicating that there are a few high values.

Front

What is a peak in a data graph?

Back

A peak in a data graph is the highest point in the distribution, representing the mode or the most frequently occurring value.

Front

What is a cluster in data distribution?

Back

A cluster in data distribution refers to a group of data points that are close together, indicating a concentration of values in that range.

Front

What does it mean for data to be symmetrical?

Back

Data is symmetrical when the left and right sides of the distribution are mirror images of each other, indicating that values are evenly distributed around a central point.

Front

What is the mode of a dataset?

Back

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

Front

How do you find the spread of data?

Back

The spread of data can be found by calculating the range, which is the difference between the highest and lowest values in the dataset.

Front

What is a bell curve?

Back

A bell curve is a graphical representation of a normal distribution, where most values cluster around the mean, creating a shape that resembles a bell.

Front

What does it mean if there is a gap in the data?

Back

A gap in the data indicates a range of values where no data points exist, suggesting a break in the distribution.

Front

What is the significance of the range in data distribution?

Back

The range provides a measure of how spread out the values are in a dataset, helping to understand the variability.
