Drawing graphs and charts. When drawing a chart or a graph, the independent variable goes on the horizontal (x) axis and the dependent variable goes on the vertical (y) axis. Once this has been ...
- Step 1: Compare The Medians of Box Plots
- Step 2: Compare The Interquartile Ranges and Whiskers of Box Plots
- Step 3: Look For Potential Outliers
Compare the respective medians of each box plot. If the median line of a box plot lies outside of the box of a comparison box plot, then there is likely to be a difference between the two groups. Source: https://blog.bioturing.com/2018/05/22/how-to-compare-box-plots/
Compare the interquartile ranges (that is, the box lengths) to examine how the data is dispersed between each sample. The longer the box, the more dispersed the data. The smaller, the less dispersed the data. Next, look at the overall spread as shown by the extreme values at the end of two whiskers. This shows the range of scores (another type of d...
When reviewing a box plot, an outlier is defined as a data point that is located outside the whiskers of the box plot.
Plot (graphics) A plot is a graphical technique for representing a data set, usually as a graph showing the relationship between two or more variables. The plot can be drawn by hand or by a computer. In the past, sometimes mechanical or electronic plotters were used.
Jan 7, 2019 · How to ‘describe’ graphs. When asked to describe patterns in graphs, you ‘say what you see’. To describe the graph in Figure 1, for example, you could say: “The rate of photosynthesis increases as temperature increases until a set temperature where the rate then falls back to zero.”. If you can see numbers on the graph’s scales ...
1. Choose simple scales. Put the dependent variable on the ‘y-axis’. and the independent variable on the ‘x-axis’. 2. Plot the points neatly. To mark the points we usually use an X. Usually you need. 5 or more points for the graph.
In the example in Figure 12.9, the X-axis of both plots is time. For the Scatter Plot, the time is in minutes and is a continuous scalar variable. In contrast, in the Line Plot the variable is the month, which can is ordinal (has a proper order) but the amount of time within and between each month can vary slightly. Figure 12.9.
