Vocabulary for Chapter 3 – Numerically Summarizing Data Arithemetic mean ‐ The arithmetic mean of a variable is computed by adding all the values of the variable in the data set and dividing by the number of observations. Population arithmetic mean ‐ The population arithmetic mean‚ µ‚ is computed using all the individuals in a population and is a parameter. Sample arithmetic mean ‐ The sample arithmetic mean‚ x ‚ is computed using sample data and is a statistic. Mean – Although other types of means exist

pictures from 2005 and numerical methods of descriptive statistics‚ one can learn how these variables play a part in the success of a motion picture. Opening Weekend Gross Sales After calculating several central tendency measures (mean‚ median‚ and mode)‚ one can create a histogram and see the opening weekend gross sales are heavily skewed to the right. The median opening gross sales of 0.39‚ indicating 50% of the opening gross sales values were less than 0.39 and 50% were greater than 0.39‚ would

central tendency for the IQ‚ income‚ and conception-to-birth data sets. In the cell range D3:F3‚ the skewness for each data set has been computed — e.g.‚ using the formula =SKEW(F8:F657) for IQs in cell D3. The median‚ mode‚ and mean for each data set have been computed using the MEDIAN‚ MODE‚ and AVERAGE functions‚ respectively. For positively skewed data sets‚ the mean is greater than the median. For negatively skewed data sets‚ the mean is less than the median. For relatively symmetric data sets‚ the

of a set of values. Mode: Advantages: Allows you to see what value happened the most in a set of data. This can help you to figure out things in a different way. It is also quick and easy. Disadvantages: Could be very far from the actual middle of the data. The least reliable way to find the middle or average of the data Comparison Of Mode With Mean and Median From the above discussion‚ about the merits and drawbacks of mean‚ median and mode it is obvious that mode does not stand in comparison
