What does it mean when a graph has a peak?

Back

A peak in a graph indicates the mode or the most frequently occurring value in the data set.

What is meant by 'skewed left' in a data distribution?

Back

A left-skewed distribution has a longer tail on the left side, indicating that the majority of the data points are concentrated on the right.

Front

How can you identify a cluster in a data set?

Back

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

Front

What does it indicate if a graph has a peak between 10 and 14 hours?

Back

It indicates that the most common value or mode of the data set falls within the range of 10 to 14 hours.

What is the significance of identifying clusters in data?

Back

Identifying clusters helps in understanding the distribution and concentration of data points, which can reveal patterns or trends.

Front

What is a data distribution?

Back

A data distribution describes how values are spread or distributed across a range, showing the frequency of each value.

Front

What is the mode in a data set?

Back

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

Front

What does a right-skewed distribution look like?

Back

A right-skewed distribution has a longer tail on the right side, indicating that most data points are concentrated on the left.

Front

How can you visually identify the shape of a data distribution?

Back

The shape of a data distribution can be identified by analyzing the graph's peaks, valleys, and overall symmetry.
