## Which of the following best describes the purpose of a histogram?

Which of the following BEST describes the purpose of a histogram.

The best answer is that a histogram measures distribution of continuous data.

A histogram is a special type of bar chart.

It can be used to display variation in weight — but can also be used to look at other variables such as size, time, or temperature..

## What type of data is best displayed in a histogram?

Answer. A “histogram” is used for plotting the occurrences of score frequency in a “continuous data set”. This data set is further divided into classes and they are referred as bins. This histogram is similar to bar charts which is used for dealing variables like nominal and ordinal data set.

## What does the shape of a histogram tell us?

This shape may show that the data has come from two different systems. If this shape occurs, the two sources should be separated and analyzed separately. … In other words, all the collected data has values greater than zero. Skewed left: Some histograms will show a skewed distribution to the left, as shown below.

## What does shape of data mean?

The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform. … A single peak over the center is called bell-shaped.

## How do you describe a distribution?

A distribution is the set of numbers observed from some measure that is taken. For example, the histogram below represents the distribution of observed heights of black cherry trees. Scores between 70-85 feet are the most common, while higher and lower scores are less common.

## How is a histogram is different than a dot plot?

Histograms subdivide data into intervals (bins), and use rectangles (usually columns) to show the frequency (count) of observations in each interval. … Dot plots include ALL values from the data set, with one dot for each occurrence of an observed value from the set.

## What is the strength of a histogram?

The strength of a histogram is that it provides an easy-to-read picture of the location and variation in a data set. There are, however, two weaknesses of histograms that you should bear in mind: The first is that histograms can be manipulated to show different pictures.

## Why are histograms misleading?

The y-axis of a histogram shows how many observations are in each group, using counts or percentages. A histogram can be misleading if it has a deceptive scale and/or inappropriate starting and ending points on the y-axis. … It also makes the data set look smaller, if you don’t pay attention to what’s on the y-axis.

## What does a histogram show that a Boxplot does not?

In the univariate case, box-plots do provide some information that the histogram does not (at least, not explicitly). That is, it typically provides the median, 25th and 75th percentile, min/max that is not an outlier and explicitly separates the points that are considered outliers.

## What are the disadvantages of using a histogram instead of a dot plot?

Disadvantages: Cannot read exact values because data is grouped into categories. More difficult to compare two data sets.

## What can you tell from a histogram?

A histogram shows bars representing numerical values by range of value. A bar chart shows categories, not numbers, with bars indicating the amount of each category. Histogram example: student’s ages, with a bar showing the number of students in each year.

## What are the weaknesses of a histogram?

Weaknesses. 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 are the pros and cons of histograms?

Pros and consHistograms are useful and easy, apply to continuous, discrete and even unordered data.They use a lot of ink and space to display very little information.It’s difficult to display several at the same time for comparisons.

## What advantage does a histogram have over a box plot?

Although histograms are better in determining the underlying distribution of the data, box plots allow you to compare multiple data sets better than histograms as they are less detailed and take up less space. It is recommended that you plot your data graphically before proceeding with further statistical analysis.

## What is an advantage of a Stemplot over a histogram?

A stem-and-leaf plot is similar to a histogram but has the advantage that the graph still contains. – the original data. – & provides an easy way to sort. What is a disadvantage of using a stem-and-leaf plot instead of a histogram? Histograms easily organize data of all sizes where stem-and-leaf plots do not.

## When would a Stemplot be better than a histogram?

Stemplots show a little more information than a histogram and have been a common tool for displaying data sets since the 1970s. They are typically used when there is a medium amount of quantitative variables to analyze; Stemplots of more than 50 observations are unusual.

## Which is not an advantage of using a histogram to represent data?

Which is not an advantage of using a histogram to represent data? Cannot read exact values because data is grouped into categories. From the graph below, find the top 2 salespeople.

## What is an advantage of using a stem and leaf plot over a histogram?

The stem and leaf plot essentially provides the same information as a histogram, with the following added benefits: The plot can be constructed quickly using pencil and paper. The values of each individual data point can be recovered from the plot.
