Introduction of elementary statistics problem:
Data is a word in a plural form of the Latin word datum. Every part of our lives utilizes data in one form or the other. This extraction of significant information is study in a branch of mathematics called statistics. A step additionally by studying certain numerical representatives of the ungrouped data, also called measures of central tendency, namely, mean, median, mode and also range are under the elementary statistics only.
I like to share this How to Find the Mean Median and Mode with you all through my article.
About Elementary statistics
Elementary statistics is deals with the basic static calculations of data’s for finding the mean values etc... The word ‘statistics’ appears to have been taken from the Latin word ‘status’ meaning ‘a state (related to a political)’... Statistics deals with collection, organization, analysis, and Interpretation of data. ‘Statistics’ has held different meanings in different contexts, so that the calculation process is based on the meaning and data. Elementary statistics problems are mainly deals with the mean, median, mode, and range.
Example for elementary statistics problems
Let us see about the basic elementary stastistics problem below,
Example for Mean: what is the mean of 3, 8 and 5?
Add the numbers: 6 + 8 + 4 = 16
divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6
so the Mean is 6
Example for Median: Find the Median of {12, 3 and 5}. Put them in order: {3, 5, 12}, the middle number is 5, so the median is 5.
Special Case: If there are two middle numbers (as happens when there are an even amount of numbers) then average those two numbers.
Find the Median of {12, 3, 5 and 2}. Put them in order: {2, 3, 5, 12}, the middle numbers are 3 and 5, the average of 3 and 5 is 4, so the median is 4.
Example for Mode: The number, which appears mostly, repeated in a set of numbers. In Set {6, 3, 9, 6, 6, 5, 9, 3} the Mode is 6.
Example for Range: is nothing but the difference between the lower and higher values.
In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9, so the range is 9-3 equals 6.
Range can also mean all the output values of a function.
