## Which type of graph best represents data as percentages?

pie graph

## What type of data are pie charts and bar graphs used for?

There are several different graphs that are used for qualitative data. These graphs include bar graphs, Pareto charts, and pie charts. Pie charts and bar graphs are the most common ways of displaying qualitative data.

**Which graph displays data in top to bottom fashion in storytelling?**

Answer. In most cases, Vertical bars will be used to display the data in a top-to-bottom fashion, so option D) Vertical Bar is the correct answer. These bars are normally used to show the time series data or other forms of data to easily identify the information available in it.

### What is not a part of storytelling with data?

Story telling with data helps us to visualize and communicate with data in a better way and leads to better understanding with the intended audience. Clutter refers to the visual elements that take up space but do not increase understanding. Eliminating Clutter does not form a part of story telling with data.

### When using bar graph the width of the bars must be?

The height or length of a bar indicates on a suitable scale the corresponding value of the numerical data. Steps while constructing bar graphs : 1) The width of the bars should be uniform throughout. 2) The gap between one bar and another should be uniform throughout.

**What is the significance of height and width of a bar?**

Each bar or column in a bar graph is of equal width and corresponds to the equal class interval. All bars have a common base. The height of the bar corresponds to the frequency of the data.

#### What does the height of a bar represents in a bar graph?

The height of a bar graph is the maximum coordinate attained by the graph, the width is the maximum coordinate and the semi-perimeter is the sum of the number up and horizontal steps.

#### How is a bar graph constructed?

A bar graph is a plot made of bars whose heights (vertical bars) or lengths (horizontal bars) represent the frequencies of each category. There is 1 bar for each category, with space between each bar, and the data that is plotted is discrete data. Each category is represented by intervals of the same width.

**What does the tallest bar on a histogram tell you?**

A histogram is a type of vertical bar graph in which the bars represent grouped continuous data. The highest peak of the histogram represents the location of the mode of the data set. The mode is the data value that occurs the most often in a data set.

## What does the sum of heights of all rectangles represent?

The height of the rectangle represents the number of times the values within an interval occurred.

## Is a histogram continuous data?

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).

**Which of the following is represented by the heights of the rectangles?**

Hence, height of the rectangle represents the frequency of the class. Was this answer helpful?

### What does the height of a rectangle show in a histogram?

Answer : The height of a rectangle in a histogram shows the number of time the particular observation occurred in the data that is frequency. Hence, the height of a rectangle in a histogram shows the Frequency of the class.

### Which graph shows two sets of data simultaneously?

double bar graph

**When data is represented using a circle it is called?**

(d) Data represented using circles is known as pie chart. Pictograph Data using pictures and symbols to represent the statistical information is known as pictograph.

#### What are class intervals in a histogram?

One of the ranges into which data in a frequency distribution table (or histogram) are binned. The ends of a class interval are called class limits, and the middle of an interval is called a class mark.

#### What is class mark of a class interval?

We know that class mark is the mid-value or central value of a class. It means that it is the average of the actual upper limit and actual lower limit for a given class. It may also be said that the mid value of every class interval is called its class mark. Therefore, the class mark for the class interval 10-20 is 15.
