Graphical Representation of Data
Examples on Graphical Representation of Data. Example 1: A pie chart is divided into 3 parts with the angles measuring as 2x, 8x, and 10x respectively. Find the value of x in degrees. Solution: We know, the sum of all angles in a pie chart would give 360º as result. ⇒ 2x + 8x + 10x = 360º. ⇒ 20 x = 360º.
Histogram
In statistics, a histogram is a graphical representation of the distribution of data. The histogram is represented by a set of rectangles, adjacent to each other, where each bar represent a kind of data. Statistics is a stream of mathematics that is applied in various fields. When numerals are repeated in statistical data, this repetition is ...
4.2: Frequency Distributions and Statistical Graphs
Frequency and Frequency Distributions. Frequency is the number of times a data value or groups of data values (called classes) occur in a data set.. A frequency distribution is a listing of each data value or class of data values along with their frequencies.. Relative frequency is the frequency divided by \(n\), the size of the sample.This gives the proportion of the entire data set ...
Histogram
A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar.. The horizontal axis displays the number range. The vertical axis (frequency) represents the amount of data that is present in each range. The number ranges depend upon the data that is being used.
Histogram
Histogram is a graphical representation that condenses data series into easy-to-understand numerical data by grouping them into logical ranges of varying heights, often known as bins. Essentially, it summarises discrete or continuous data. ... In a histogram data is grouped into continuous number ranges and each range corresponds to a vertical ...
Graphical Representation
General Rules for Graphical Representation of Data. There are certain rules to effectively present the information in the graphical representation. They are: Suitable Title: Make sure that the appropriate title is given to the graph which indicates the subject of the presentation. Measurement Unit: Mention the measurement unit in the graph.

2.2: Histograms, Ogives, and Frequency Polygons
Table 2.2.7: Data of Test Grades. Solution: Since this data is percent grades, it makes more sense to make the classes in multiples of 10, since grades are usually 90 to 100%, 80 to 90%, and so forth. It is easier to not use the class boundaries, but instead use the class limits and think of the upper class limit being up to but not including ...
Ch. 2 Key Terms
a data representation in which grouped data is displayed along with the corresponding frequencies Histogram a graphical representation in x-y form of the distribution of data in a data set; x represents the data and y represents the frequency, or relative frequency. The graph consists of contiguous rectangles.
Image from Pixabay. AKA: Column Histograms. Why: a histogram is a graphical representation of the distribution of a dataset.Although its appearance is similar to that of a standard bar graph, instead of making comparisons between different items or categories or showing trends over time, a histogram is a plot that lets you show the underlying frequency distribution or the probability ...
2: Graphical Representations of Data
2.3: Histograms, Frequency Polygons, and Time Series Graphs. A histogram is a graphic version of a frequency distribution. The graph consists of bars of equal width drawn adjacent to each other. The horizontal scale represents classes of quantitative data values and the vertical scale represents frequencies. The heights of the bars correspond ...
2.4: Measures of Central Tendency- Mean, Median and Mode
a data representation in which grouped data is displayed along with the corresponding frequencies Mean a number that measures the central tendency of the data; a common name for mean is 'average.' The term 'mean' is a shortened form of 'arithmetic mean.' By definition, the mean for a sample (denoted by \(\bar{x}\)) is \(\bar{x} = \dfrac{\text ...
Definition, Types, Uses, How to Draw Bar graph, Examples
When the grouped data are represented vertically in a graph or chart with the help of bars, where the bars denote the measure of data, such graphs are called vertical bar graphs. ... A pie chart is one of the types of graphical representation. The pie chart is a circular chart and is divided into parts. Each part represents the fraction of a ...

Histogram is a graphical representation used to create a graph with bars representing the frequency of grouped data in vector. Histogram is same as bar chart but only difference between them is histogram represents frequency of grouped data rather than data itself. Syntax: hist(x, col, border, main, xlab, ylab) where: x is data vector

Cumulative Frequency Curve : Concepts, Examples, Graphs
So let us study the graphical representation of Cumulative Frequency Curve data. As we know, a picture speaks a thousand words. In the world of statics, graphs, in particular, are very important, as they help us make sense of the data and understand it better. ... A curve that represents the cumulative frequency distribution of grouped data on ...
Frequency Measures and Graphical Representation of Data
Thus we conclude, based on the grouped data, that only about 42% of the deliveries were completed in the desired time frame. 3 Graphical Representation of a Variable Frequency tables and empirical cumulative distribution functions are useful in providing a numerical summary of a variable.
Frequency Distribution
Frequency Distribution Table for Grouped Data. A grouped frequency distribution table is a table that organizes any given data into intervals or ... also known as a frequency curve, is a graphical representation of a data set's frequency distribution. It is used to visualize the distribution and frequency of values or observations within a ...
17 Important Data Visualization Techniques
Some data visualization tools, however, allow you to add interactivity to your map so the exact values are accessible. 15. Word Cloud. A word cloud, or tag cloud, is a visual representation of text data in which the size of the word is proportional to its frequency. The more often a specific word appears in a dataset, the larger it appears in ...
PDF Lecture.3 Graphical representation
Graphical representation - Histogram - Frequency polygon and Frequency curve Graphs Graphs are charts consisting of points, lines and curves. Charts are drawn on graph sheets. Suitable scales are to be chosen for both x and y axes, so that the entire data can be presented in the graph sheet.

2.3 Stem-and-leaf plot. A stem-and-leaf plot is a graphical device that is useful for representing a relatively small set of data which takes numerical values. To construct a stem-and-leaf plot, we partition each measurement into two parts. The first part is called the stem, and the second part is called the leaf.
Frequency Distribution and Data: Types, Table, Graph, Videos
Frequency distribution in statistics provides the information of the number of occurrences (frequency) of distinct values distributed within a given period of time or interval, in a list, table, or graphical representation.Grouped and Ungrouped are two types of Frequency Distribution. Data is a collection of numbers or values and it must be organized for it to be useful.
