Since the independent variable is categorical and the dependent variable is continuous, this graph should be a bar graph. Assuming this was a randomized clinical trial Yum. 2. Many graphs are used to concisely and clearly summarize data; the best type of graph to use depends on the type of data being conveyed (such as nominal, scale-discrete, scale-continuous and ordinal). In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. Before multiplying the two, make sure that they have the same unit, whether it is in centimeters of in meters.

May use scale break to accommodate all data. All of these depend on the person who is making the observation someone else might make these measurements differently. when graphing your data it is important to quizlet If the values are continuous, they need to be evenly spaced based on the value. Continuous data are measured on a scale or continuum (such as weight or test scores). If the data sets have different means and standard deviations, then comparing the data values directly can be misleading. That is, just presenting a series of data as randomnumbers that bear little apparent relationship to one another is often difficult to interpret.
