HISTOGRAMS

Front

What is a histogram?

Back

A histogram is a graphical representation of the distribution of numerical data, showing the frequency of data points within specified intervals.

Front

What does the shape of a histogram indicate?

Back

The shape of a histogram indicates the distribution of the data, such as whether it is skewed left, skewed right, or symmetrical.

Front

What is an interval in a histogram?

Back

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

Front

What does it mean if a histogram is skewed right?

Back

If a histogram is skewed right, it means that most of the data points are concentrated on the left side, with fewer data points on the right.

Front

How do you determine the frequency of a data set in a histogram?

Back

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

Front

What is the importance of labeling axes in a histogram?

Back

Labeling axes is important because it provides context for the data, indicating what the intervals and frequencies represent.

Front

What is the effect of overlapping intervals in a histogram?

Back

Overlapping intervals can lead to confusion and misinterpretation of the data, making it difficult to accurately assess the frequency.

Front

How can you identify the mode from a histogram?

Back

The mode can be identified as the interval with the highest frequency in the histogram.

Front

What is the range of data in a histogram?

Back

The range of data is the difference between the highest and lowest values in the data set.

Front

What does it mean if a histogram starts at a value greater than 0?

Back

If a histogram starts at a value greater than 0, it may misrepresent the data, as it does not show the full range of values.
