This clip examines how the mean, median and mode can each tell a different story about the same set of data. As an example, the clip looks at the number of newspapers sold at a convenience store on seven consecutive days, and asks whether the mean, ...
This clip introduces and defines the terms "mean," "median" and "mode."
This clip defines and offers examples of outliers and explains the impact they can have on the mean. "The median can be a better statistic to use when the data set includes outliers," the clip explains.
This clip explains that many real-life applications of statistics use very large data sets. "Since there are so many values," the clip states, "Â…and some of the values appear more than once, we'll group the data in a table." The clip concludes by n...
This clip presents two examples showing how data can be skewed by advocates looking to make a particular point, simply by choosing to use (or not use) the mean, median or mode in analyzing a data set.
This clip explains that the mode is the most frequently occurring value in a set of data. The clip goes on to state that a set of data can have more than one mode, and the mode isn't affected by outliers. "In fact, the mode could be an outlier in a ...
This clip explains that the mean is the most common statistical measurement: the arithmetic average. "It is the sum of all the values, divided by the number of values in the data set," the clip states. The clip also includes two examples of how the ...
This clip reviews the essential points about "mean," "median" and "mode." It notes that the mean uses more information from the data set than the median or the mode, but can be influenced by outliers. The median tells us the number in the middle of ...
This clip uses test scores to illustrate how the mean value can be determined and then utilized to set goals for future test results.
This clip explains that the median is the number in the middle of the data set when values are put in a numerically ordered sequence called an array. If the data set contains an outlier, the median may be a better statistic to use than the mean. As ...
