1.The mean is a form of measurement for central tendency.
2. A table is a symbolic or pictorial display of numerical information.
3. To find the mean, total the values in a group and multiply the sum by the number of value added.
4 A pie chart is normally used to illustrate trends.
5 An example of non visual data presentation is the bar graph.
6 A smaller standard deviation indicated that the mean is a typical value in the data set.
7 To find the standard deviation you only need to know the mode.
