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 more lower 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 more higher values.

Front

What is a mode in a dataset?

Back

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

Front

What is a peak in a graph?

Back

A peak in a graph represents the highest point of data, indicating where the most frequent values occur.

Front

What does it mean if data is symmetrical?

Back

If data is symmetrical, it means that the left and right sides of the distribution are mirror images of each other.

Front

What is a bi-modal distribution?

Back

A bi-modal distribution has two different modes or peaks, indicating two different groups within the data.

Front

What is a cluster in data?

Back

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

Front

What is the spread of data?

Back

The spread of data refers to how far apart the values are from each other, often measured by range, variance, or standard deviation.

Front

What is a gap in data?

Back

A gap in data is a space where no data points exist, indicating a lack of values in that range.
