By the frequency of a number we mean the number of occurrence of that number. 3) How do I do it? GRAPHICAL REPRESENTATIONS OF DATA Math Notes in 7.1 Students represent distributions of single-variable data numerical data using dot plots, stem-and-leaf plots, box plots, and histograms. That is, in histogram rectangles are erected on the class intervals of the distribution.

In addition to the pictures, you can add words, also called labels to indicate what the pictures represent. Plot Area Line plots are graphical representations of numerical data. Each representation communicates information in a slightly different way. PivotChart: A graphical representation of the data in a PivotTable. The usefulness of different graph types will vary depending upon the number of intervals and the type of data being represented. For example, a pie chart of our weight data is difficult to read because of the quantity of intervals we used. That is, you should prepare it. Charts are graphical representation of worksheet data. Other graph types such as pie charts are possible for quantitative data. 2) Charts make the data of a worksheet easier to understand. A set of data that describes and gives information about other data. They represent categorical one-variable data on bar graphs. Active Cell: This activity was created by a Quia Web subscriber. When you select a cell, when you click on a cell, when you are ready to type in a cell, what is that cell called? What is a chart or graph? Histogram. What is a Chart? • The practice of keeping a separate worksheet for “Metadata” is an efficient way of keeping track of the small details of the variables in your data sheets for your future self or other people • The column headings can be transposed into a the first column of a new worksheet called “Metadata” A graphic representation of data in a worksheet Based on descriptive (text) entries called category labels and numeric values called data points Data series: a grouping of data points A graphic representation of data in a worksheet Based on descriptive (text) entries called category labels and numeric values called data Password: Text that must be entered before a user can access a secured workbook, worksheet, or worksheet elements. A graphical representation of worksheet data. Data analysis on charts is done using graphics that present pictures. A line plot is a number line with x’s placed above speciﬁc numbers to show their frequency. The areas of rectangle are proportional to the frequencies. Data visualization is the graphical representation of information and data. By using visual elements like charts, graphs, and maps, data visualization tools provide an accessible way to see and understand trends, outliers, and patterns in data. In histogram, the bars are placed continuously side by side with no gap between adjacent bars. Because a chart is used to present data in a graphical format, before creating a chart, you should plan it. Line plots are used to represent one group of data with fewer than 50 values. Highlight data on the worksheet for the chart, then either choose Insert, Chart OR the Chart button from the toolbar. Data when represented in the form of charts makes it easier for users to quickly understand, compare and find patterns and relationships. PivotTable: A highly configurable table that condenses large amounts of data. A two dimensional graphical representation of a continuous frequency distribution is called a histogram. STEM-AND-LEAF-PLOTS In Excel, charts are used to make a graphical representation of any set of data. 1) A chart is a graphical representation of data contained a worksheet.
