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 does it mean if data is skewed left?

Back

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

What is a symmetrical distribution?

Back

A symmetrical distribution is one where the left and right sides of the graph are mirror images of each other, indicating that data is evenly distributed around the mean.

Front

What is a peak in a data distribution?

Back

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

Front

What is a cluster in data distribution?

Back

A cluster is a group of data points that are close together, indicating a concentration of values in a specific range.

Front

What is a gap in data distribution?

Back

A gap is an area in a data distribution where there are no data points, indicating a lack of values in that range.

Front

What is an outlier?

Back

An outlier is a data point that is significantly different from other observations in the dataset, often lying far away from the mean.

Front

What is the mode of a dataset?

Back

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

How can you identify the shape of a data distribution?

Back

You can identify the shape of a data distribution by analyzing the graph for symmetry, skewness, peaks, and gaps.
