X is the Mean (not mode.. mode is the most common, mean is the sum of all numbers divided by the number of numbers there are in the data set) :
I dont think there is a symbol for mode, ill ask my teacher tomorrow morning ;)
properties of mode as used in statistics
There is no specific symbol for the mode.
The mode is the number in a set which repeats the most.
In statistics, this is the symbol for the "Variance"
descriptive statistics
They are about the central tendency of a set of data, Here is a set of 10 pieces of data 1+2+3+5+5+5+6+7+8+8data 1,2,3 5,5,5,6,7,8,8. Mean ; Add the data and divide by the number of terms Hence {1+2+3+5+5+5+6+7+8+8] / 10 => 50/10 => 5 The mean Median The Absolute centre of the set of data , which is '5'. Mode The term that occurs most frequently, which is also '5'. as it occurs three times.
When data are nominal.
Examples of descriptive statistics are mean, median, mode, and midrange.
