Excel 97, however, introduced an optimization that attempts to correct for this problem. Should an addition or subtraction operation result in a value at or very close to zero, Excel 97 and later will compensate for any error introduced as a result of converting an operand to and from binary. The example above when performed in Excel 97 and later correctly displays 0 or 0.000000000000000E+00 in scientific notation.

A mean calculated in this way is called a grouped mean. A grouped mean is not as precise as the mean calculated from the original data points, but it is often your only option if the original values are not available. Consider the following grouped data set in Figure 4-4.

There is no absolute agreement among statisticians about how to define outliers, but nearly everyone agrees that it is important that they be identified and that appropriate analytical techniques be used for data sets that contain outliers. An outlier is a data point or observation whose value is quite different from the others in the data set being analyzed. This is sometimes described as a data point that seems to come from a different population or is outside the typical pattern of the other data points. Suppose you are studying educational achievement in a sample or population, and most of your subjects have completed from 12 to 16 years of schooling (12 years = high school graduation, 16 years = university graduation). However, one of your subjects has a value of 0 for this variable (implying that he has no formal education at all) and another has a value of 26 (implying many years of post-graduate education). You will probably consider these two cases to be outliers because they have values far removed from the other data in your sample of population. Identification and analysis of outliers is an important preliminary step in many types of data analysis because the presence of just one or two outliers can completely distort the value of some common statistics, such as the mean.

The histogram is another popular choice for displaying continuous data. A histogram looks similar to a bar chart, but in a histogram, the bars (also known as bins because you can think of them as bins into which values from a continuous distribution are sorted) touch each other, unlike the bars in a bar chart. Histograms also tend to have a larger number of bars than do bar charts. Bars in a histogram do not have to be the same width, although frequently they are. The x-axis (vertical axis) in a histogram represents a scale rather than simply a series of labels, and the area of each bar represents the proportion of values that are contained in that range. 2b1af7f3a8
