### Histograms are used to display :

• A.

Categorical data

• B.

Numerical data

• C.

All data types

• D.

I don't know

B. Numerical data
Explanation
Histograms are used to display numerical data. A histogram is a graphical representation that organizes data into bins or intervals and displays the frequency or count of data points falling into each bin. It is commonly used to visualize the distribution of numerical data, such as the frequency of different values or the shape of the data distribution. Categorical data, on the other hand, is better represented using bar charts or pie charts. Therefore, the correct answer is numerical data.

A. Histogram
Explanation
The correct answer is Histogram. A histogram is a graphical representation that organizes data into intervals and displays the frequency of occurrences in each interval. It consists of bars, where the height of each bar represents the frequency or count of data points falling into that interval. In this graph, the data is organized into intervals, and the bars represent the frequency of occurrences in each interval, making it a histogram.

A. Histogram
Explanation
The graph above is a histogram because it displays the distribution of a single variable by dividing it into intervals and showing the frequency or count of observations within each interval. Histograms are commonly used to visualize the shape and spread of data, making them useful for analyzing patterns and trends.

A. Histogram
Explanation
The given correct answer is "Histogram" because a histogram is a graphical representation that organizes data into intervals or bins and displays the frequency or count of data points within each interval. It is typically used to show the distribution or pattern of a dataset. In a histogram, the x-axis represents the intervals or bins, and the y-axis represents the frequency or count. The bars in a histogram are adjacent to each other and touch each other, without any gaps. Therefore, based on this description, the graph above can be identified as a histogram.

A. Histogram
Explanation
The correct answer is Histogram. A histogram is a graphical representation that organizes data into intervals or bins and displays the frequency or count of data points falling into each bin. It is commonly used to show the distribution of a continuous variable. In a histogram, the bins are represented by adjacent rectangular bars, where the height of each bar corresponds to the frequency of data points in that bin. This type of graph allows for easy visualization of the shape, center, and spread of the data.

A. Histogram
Explanation
The correct answer is Histogram. A histogram is a graphical representation of data that uses bars to represent the frequency distribution of a set of continuous or discrete data. In a histogram, the height of each bar represents the frequency or count of data within a specific range or bin. It is commonly used to visualize the distribution of numerical data and identify patterns or trends.

B. Bar Chart
Explanation
The graph above is a bar chart because it represents data using rectangular bars of equal width. Each bar corresponds to a specific category or group, and the height of the bar represents the value or frequency of that category. In a bar chart, the bars are not segmented or separated, but rather continuous and adjacent to each other.

B. Bar Chart
Explanation
The graph above is a bar chart because it represents categorical data using rectangular bars of equal width. Each bar corresponds to a specific category, and the height of the bar represents the frequency or value associated with that category. The bars are not segmented or separated, and there is no indication of any specific segmentation or separation in the graph. Therefore, the correct answer is a bar chart.
