What is the primary purpose of interpreting histograms?

• To create visually appealing graphs

• To understand the shape, center, spread, and outliers in a dataset

• To compare different datasets visually

• To calculate the mean and median of a dataset

What does the 'center' in a histogram represent?

• The highest frequency in the dataset

• The approximate location where the distribution is balanced

• The total number of observations in the dataset

• The range of possible values in the dataset

What does 'spread/variability' in a histogram indicate?

• The total number of observations

• The range and how spread out the values are

• The shape of the distribution

• The center of the distribution

What type of information does the 'shape' of a histogram provide?

• The number of observations in the dataset

• The type of variable being measured

• The overall pattern of the distribution

• The range of possible values

What is an outlier in a data distribution?

• An observation that falls within the overall pattern of the distribution.

• An individual observation that falls outside the overall pattern of the distribution.

• A value that is always naturally occurring.

• A measurement error that aligns with the distribution.

What should you do when you encounter an outlier in a dataset?

• Ignore it and proceed with the analysis.

• Investigate the observation further.

• Assume it is a naturally occurring value.

• Remove it immediately from the dataset.
