How to calculate central tendency

    • What is central tendency?

      Central Tendency is the single value that describes the full data set given by finding the central spot of that data set itself. This is often considered as the summary of the statistics or Statically Average since Functionally, it is the simple mathematical value which represents the whole data set.

    • What are the different types of central tendency measures?

      The three commonly used measures of central tendency are the mean, median, and mode. A statistic that tells us how the data values are dispersed or spread out is called the measure of dispersion. A simple measure of dispersion is the range. The range is equivalent to the difference between the highest and least data values.

    • What is the advantage of using the center statistic over the mean?

      Takeaway: A measure of central tendency is useful because it provides us with a single value that describes the “center” of a dataset. This helps us understand a dataset much more quickly compared to simply looking at all of the individual values in the dataset. The most commonly used measure of central tendency is the mean.

      Measures that indicate the approximate center of a distribution are called measures of central tendency. Measures that describe the spread of the data are measures of dispersion. These measures include the mean, median, mode, range, upper and lower quartiles, variance, and standard deviation.

      So, the solution is simple and can be programmed as follows: mean(GSS2016$age, na.rm=TRUE) GSS2016$age[GSS2016$age==99]=NA Tip: The addition of the code na.rm=TRUE tells R to remove the unknown entries from the list that will be used to make calculations (in this case for the mean). 49.15576
