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.

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).
Which central tendency is used most often with range?
It could be the mean or the median.
Which of the arithmetic mean median and mode are resistant measures of central tendency?
Of these three, the median is most resistant.
What type of statistics are mean median and mode?
They are statistics of central tendency.
What are the criteria for choosing measure of central tendency and measure of variation?
Central tendency is measured by using the mean, median and mode of a set of numbers. Variation is measured by using the range, variance and standard deviation of a set of numbers.

What does central tendency mean in math terms?
Measures of central tendency are the mean, median, range, mode ect.
Which central tendency is used most often with range?
It could be the mean or the median.
What do you mean by measures of central tendency and dispersion?
Common measures of central tendency are the mean, median, mode. Common measures of dispersion are range, interquartile range, variance, standard deviation.
Which is not an average mean mode range and median?
The range is not an average. Also, the mode is not a measure of central tendency - which an average is. A skew distribution is likely to have the mode at one end or the other and that mode would not be considered an average by any statistician.
Is median used for when there is a wide range of numbers?
If the wide range is evenly spread between the very small and the very large (the distribution is symmetric) then there is not much to choose between the median and the mean. If not, the median will have some advantages as a measure of central tendency.
Why are mean median and mode considered measures of central tendency?
The mean (average value), the median (middle value), and the mode (most frequently occurring value) are all important values.
What is the prime measure of central tendency is the?
Median
Which measure summarizes all of the values of a data set with a single number?
The central tendency can be summarised by the mode, median or mean. For qualitative data, only the mode is available.The central tendency can be summarised by the mode, median or mean.

Why do we use mean median mode and range to solve math problems?
We use mean for measure the central tendency and mode for observed most common value of observation.
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 are different measures of central tendency?
Mean median and mode
