What is a histogram?

Back

A histogram is a type of bar graph that represents the frequency distribution of numerical data. It shows how many data points fall within specified ranges (bins).

Front

What are bins in a histogram?

Back

Bins are the intervals or ranges into which data is grouped in a histogram. Each bin represents a specific range of values.

How do you determine the height of a bar in a histogram?

Back

The height of a bar in a histogram represents the number of data points that fall within the corresponding bin.

Front

What is the purpose of a histogram?

Back

The purpose of a histogram is to provide a visual representation of the distribution of data, making it easier to see patterns, trends, and outliers.

Front

How can you find the mode from a histogram?

Back

The mode can be found by identifying the bin with the highest bar, which indicates the range with the most data points.

Front

What does it mean if a histogram is skewed to the right?

Back

A right-skewed histogram indicates that most data points are concentrated on the left side, with a few larger values stretching the tail to the right.

Front

What does it mean if a histogram is symmetric?

Back

A symmetric histogram indicates that the data is evenly distributed around a central value, with similar frequencies on both sides.

Front

How can you find the median from a histogram?

Back

To find the median from a histogram, you need to determine the cumulative frequency and locate the middle value.

Front

What is the difference between a histogram and a bar graph?

Back

A histogram displays the distribution of numerical data using bins, while a bar graph represents categorical data with distinct categories.

Front

What is frequency in the context of a histogram?

Back

Frequency refers to the number of occurrences of data points within a specific bin in a histogram.
