find the (a) mean, (b) median, (c) mode, and (d) midrange for the given sample data. Express answers with the appropriate units of measurement. Then answer the given questions. Listed below are speeds (in mi/h) of cars on the New Jersey Turnpike. All cars are going in the same direction, and all of the cars are from New Jersey. The speeds were measured with a radar gun and the researchers observed the races of the drivers. The data are from Statlib and the authors are Joseph Kadane and John Lamberth. Does it appear that drivers of either race speed more than drivers of the other race?

Key Concepts

Comparative Analysis of Groups

Comparative analysis involves examining statistics across different groups to look for potential differences or trends. In the context of this problem, it includes determining whether the central tendency measures (such as mean, median, mode, and midrange) differ between groups, which can lead to insights about group behavior or characteristics.

Units of Measurement

When calculating statistical measures, it is important to include the appropriate units of measurement to ensure that the results are meaningful and interpretable in the context of the physical quantities being analyzed.

Midrange

The midrange is calculated as the average of the maximum and minimum values in the dataset. It provides a quick sense of the central position but is highly sensitive to outliers.

Mean

The mean is the arithmetic average of a set of numbers, computed by summing all the values and dividing by the number of values. It provides a measure of the central location of the data, though it can be influenced by extreme values.

Median

The median is the middle value of an ordered dataset. This measure is robust to outliers and skewed data since it simply identifies the point at which half the data lies above and half lies below.

Mode

The mode is the value or values that appear most frequently in a dataset. This measure is particularly useful when identifying the most common or typical data point, especially in categorical or discrete data.
