Comparing cumulative frequency graphs and box plots

Frequency plots can be made in Stata using the hist command with the freq option.. hist mpg, freq . hist rep78, freq However, if the variable you are graphing takes on noninteger values, this command will not work. The frequency of a particular data value is the number of times the data value occurs. For example, if four students have a score of 80 in mathematics, and then the score of 80 is said to have a frequency of 4. The frequency of a data value is often represented by f. Presentation on theme: "Cumulative Frequency and Box Plots."— covered plotting a Cumulative Frequency graph We have learnt how to interpret the graph We now know how to work out the Median, Lower and Upper Quartiles, as well as the Inter-Quartile range Today we will be plotting box...the data, complete the cumulative frequency table and construct a cumulative frequency histogram on the grid below. 8) The accompanying diagram is an example of which type of graph?

If the number of group you need to represent is high, drawing them on the same axis often results in a cluttered and unreadable figure.. A good workaroung is to use small multiple where each group is represented in a fraction of the plot window, making the figure easy to read.
The lengths of the bars represent frequency or cost (time or money), and are arranged with longest bars on the left and the shortest to the right. In this way the chart visually depicts which situations are more significant. Pareto Charts are used in cases: -When analyzing data about the frequency of problems or causes in a process.
Dec 06, 2019 · Notice that the graph of an exponential function on a semi-log graph is a straight line. Notice also that the numbers along the x axis are evenly spaced, while along the y-axis, we have powers of 10 evenly spaced. Finally, here's the graph of `y=5^x` on lin-log (linear vertical axis, logarithmic horizontal axis).
Box Plots. Go to Graph > Boxplot. Choose a graph type from the top or bottom row. "Simple Y" here means that the data are in a single column, "Multiple Y's" means several columns. Choose "With Groups" if there is an additional column of categorical variables for classification. This will allow you to make side-by-side boxplots for comparison.
