Histogram Flashcard

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, where the data is divided into intervals (bins) and the frequency of data points in each interval is represented by the height of the bars.

What does the horizontal axis of a histogram represent?

Back

The horizontal axis of a histogram is labeled as the quantitative variable, which represents the intervals or bins of the data.

Front

What is an interval in the context of a histogram?

Back

An interval is a range of numbers that groups data points together in a histogram.

Front

How do you determine the frequency of a histogram?

Back

The frequency of a histogram is determined by counting the number of data points that fall within each interval.

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 identify patterns, trends, and outliers.

Front

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

Back

If a histogram is skewed to the right, it means that the majority of the data points are concentrated on the left side, with fewer high values extending to the right.

Front

What does it mean if a histogram is symmetric?

Back

If a histogram is symmetric, it means that the data is evenly distributed around the center, with similar frequencies on both sides.

Front

What is the mode in a histogram?

Back

The mode in a histogram is the interval with the highest frequency, indicating the most common value range in the data set.

Front

How can you identify outliers in a histogram?

Back

Outliers in a histogram can be identified as bars that are significantly lower or higher in frequency compared to the other bars, indicating data points that fall outside the expected range.

Front

What is cumulative frequency in a histogram?

Back

Cumulative frequency is the running total of frequencies up to a certain interval, showing how many data points fall below a specific value.
