Which measure of central tendency represents the middle number in a set of data?
The median.
Why are mean median mode and range considered measures of central tendency?
Range is NOT a measure of central tendency. In a number of distribution - though by no means all - the mean, median and mode are near the middle of the distribution. That is more likely to be the case with a large number of observations (or experiments).
What is the purpose of central tendency measures?
It is a measure of the middle or central value of a variable of interest. There are different measures of central tendency and their purposes are not exactly the same. However, the basic principle is that the observed values of the variable are more likely to be near the central tendency value than far from them. Some central tendency values cannot ever be observed. A normal number cube, for example, has a mean value of 3.5 but you cannot possibly throw a 3.5!
What are the four measures of central tendency?
The four measures of central tendency are mean-also called average, mode-the most frequently occurring numerical, median-the middle number after arranging all data from lowest to highest numerical and lastly standard deviation-root-mean-square or square-root of the variance. These are the 4 measure of central tendency.
Why are mode median range and mean considered tendency?
Mode is the number that occurs most often in a set of data. It is considered an indication of central tendency, because in normally distributed data, the numbers that occur most often tend to be in the center of the data. Mean is the sum of all values divided by the number of values. It is a measure of central tendency, because it is a way of calculating the average value. Median is the number that has equal number of values on each side of it when the values are ordered, or the mean of the two values that have equal values on either side if the number of values is even. It is also a way of saying what is the central tendency. Range is the largest value minus the smallest value. It is a measure of how closely grouped the data is.
Which measure of central tendency represents the middle number in a set of data?
The median.
True or false A measure of central tendency is one number that describes a set of data?
True-as in an average.
Which measure of central tendency is most affected by adding a really large or small number to a data set?
Mean
Which measure of central tendency equals the sum of the data values in a set divided by the number of data values?
mean
What measure of central tendency is found by adding the data then dividing by the number of items in the set of data?
the mean or the average
Why are mean median mode and range considered measures of central tendency?
Range is NOT a measure of central tendency. In a number of distribution - though by no means all - the mean, median and mode are near the middle of the distribution. That is more likely to be the case with a large number of observations (or experiments).
What is an arithmetic mean?
An arithmetic mean is a measure of central tendency of a set of values computed by dividing the sum of the values by the number of values.

What is central tendency?
Though mean, median, and mode is central tendency, it is hard to put this into words.For an example:Your average grade in math class is an A. Though, how did you calculate that average? Well, since average means mean, you calculated that average using the method of central tendency, or in this situation, you found the mean.In other words, central tendency is just a method (mean, median and mode) to find the average, middle, and most occurring score or number in a set of data.I hope this helped! ;D~Lovingless
What is the mode if each number occurs only once?
There is no mode. One of the weaknesses of mode, as a measure of central tendency, is that there may be none, one or many modes.
