Scienctific Principles

data which is measured and usually expressed numerically (distance, time, temperature, test scores)

• Quatitative

• categorical

data that is described rather than measured (color, shape, smell, opinions)

• Quantitative

• Qualitative

During an obesity research project, a health worker categorized the weights of all incoming male freshmen at a certain university. The statistics associated with the data are presented in the table below. Which type of chart is best for this data set?

• Dot Plot

• Stem-and-Leaf Plot

• Box Plot

• Histogram

a graph in which a circle is divided into sectors that each represent a proportion of the whole. Pie charts are helpful when displaying the relative distribution of categories.

• Bar Graph

• Pie Chart

• Line Graph

• Histogram

a visual representation of data which compares values in different categories

• Bar Graph

• Pie Chart

• Line Graph

• Histogram

a visual representation of data which compares frequencies of different numeral intervals

• Bar Graph

• Histogram

• Box Plot

• Line Graph

A variable that is manipulated by the scientist conducting the experiment to see if that causes a change

• Controlled variable

• Dependent Variable

• Independent variable

• Variable

a variable that is kept stable throughout the experiment, across control and experimental groups, to ensure that any difference in the dependent variable is because of the independent variable.
