# Can a histogram have gaps?

A histogram has an appearance similar to a vertical bar graph, but when the variables are continuous, there are no gaps between the bars. When the variables are discrete, however, gaps should be left between the bars. In a histogram, frequency is measured by the area of the column.

## Can a histogram have gaps?

A histogram has an appearance similar to a vertical bar graph, but when the variables are continuous, there are no gaps between the bars. When the variables are discrete, however, gaps should be left between the bars. In a histogram, frequency is measured by the area of the column.

## What does it mean when there is a gap in a histogram?

A gap is a class or classes having frequency zero, but with non-zero frequency classes on both sides. Extreme values are data values which are separated from other data values by a gap at least two classes wide.

## What can a histogram tell you?

It will help you determine the number of bars, the range of numbers that go into each bar, and the labels for the bar edges.

## Which statement about histograms is true?

The correct answer is b) Histograms can be used to exhibit the shape of distributions.

## What are the weaknesses of a histogram?

Histograms have many benefits, but there are two weaknesses. A histogram can present data that is misleading. For example, using too many blocks can make analysis difficult, while too few can leave out important data.

## What is the best title for the graph?

Titling the Graph The proper form for a graph title is “y-axis variable vs. x-axis variable.” For example, if you were comparing the the amount of fertilizer to how much a plant grew, the amount of fertilizer would be the independent, or x-axis variable and the growth would be the dependent, or y-axis variable.

## What is the formula for histograms?

Histogram Formula – Example #1 Frequency density of the first interval = 2 / 5 = 0.4. Frequency density of the second interval = 7 / 10 = 0.7. Frequency density of the third interval = 21 / 5 = 4.2. Frequency density of the fourth interval = 15 / 5 = 3.0.

## What is the title of this bar graph?

A bar graph is a two-dimensional display of data in a bar format. This format allows you to compare characteristics and frequencies such as quantity and price between and within groups of data. Required bar graph titles include the name of the graph, the title of the vertical axes, and the title of the horizontal axes.

## What is the uses of histogram?

A histogram is used to summarize discrete or continuous data. In other words, it provides a visual interpretation. This requires focusing on the main points, factsof numerical data by showing the number of data points that fall within a specified range of values (called “bins”). It is similar to a vertical bar graph.

## What best describes the purpose of bar graphs?

The right answer is They compare quantities for particular categories. The bar graph is composed of horizontal bands. It draws attention to the comparison of values rather than a period followed by time (as in the case of the bar chart).

## What does it mean to normalize a histogram?

Histogram normalization is a common technique that is used to enhance fine detail within an image. Each column in the cumulative histogram is computed as the sum of all the image intensity histogram values up to and including that grey level, and then it is scaled so that the final value is 1.0.

## Why is there no gaps in a histogram?

This is because a histogram represents a continuous data set, and as such, there are no gaps in the data (although you will have to decide whether you round up or round down scores on the boundaries of bins).
