Quartile,Deciles And Percentiles

 Today  we will see some important measures of central tendency called Quartile,Deciles and Percentiles...

1)Quartile

Three variate  value of the variables which divides the series(data) into four equal parts are called Quartiles. There  are three quartiles namely Q1,Q2 and Q3.Q1 is known as lower or first quartile,Q2 is  the second quartile (median) and last one Q3 is known as upper or third quartile.25% values are less then Q1 and 25% values are larger than Q3 and the rest 50% values lie between Q1 and Q3.And Q2 devides data into two equal parts and due to this this is also known as median.The quartiles can help us to find some insights of given data set.These widely used in data analytics and economics.By these values we can about shape of distribution.

2)Deciles

The variate value of the variables which divides the series(data) into ten equal parts are known as Deciles.They are denoted by D1,D2....so on.fifth decile divides data into two parts so it is called as median.

3)Percentiles

The values of the variable which divides data into 100 equal parts are called percentiles.fiftieth percentile will be median as it divides data in two equal parts.

Median

Image
  Median Median is the value of the variable that divides the ordered set of values into two equal parts. In another words,median is the middle most value of ordered( ascending or descending)set of values.50% of values are to the left side of the median and 50% values are on right side of the median. let us consider there are N values in the data set. I)when N is odd,then  Median=size of(N+1/2) th item(Arranging values in ascending or descending order) Example:  values =1,2,3,4,5 here,Median is 3 II) when N is even , median is the average of size of (N/2)th item and (N+2/2) th item. Example: Heights (in cm) = {180, 167, 154, 122, 181, 135, 123, 145, 166, 145} Rearranged Heights= {122, 123, 135, 145, 145, 154, 166, 167, 180, 181} Median = (145+154)/2 = 149.5= 149.5 Median is preferable measure of location for asymmetric distribution.Median is best measure of central tendency as it is least affected by extreme values.Median can be visually located for discrete values....

Mode

Image
Mode : Mode is an important measure of central tendency.Ya Lun Chou statement about the mode is ,"Mode is that values of series which appears most frequently than any other." In simple  words,"The mode is a value which has highest frequency." The mode may not be unique .that is there are several values or classes with the same highest frequency. I) Mode for discrete data:      Mode of sample is the observation with highest frequency. Example: A sample is 4,8,3,8,3,9,3,7,11,3,12,11 Here number 3 has maximum frequency(4). Hence given sample has mode 3. II)Mode for grouped data:      Mode of grouped data is the class centre of the modal class,while the modal class is a class which has highest frequency. Example Here 10-20 class has maximum frequency (15). Hence 10-20 is modal class. Here L=10,f1=15,fo=5,f2=8,h=20-10= 10 Mode=10+[(15-5)/(30-5-8)]×10 Mode=10+(10/17)×10 Mode=10+5.88 Mode=15.88 For example,In clothing Store,they operate their business to incl...

Sample space and event in probability

Image
  Sample space and Event Sample space:  A collection of all possible outcomes of an experiment is called sample space.It is denoted by  Ω. Example: A coin is tossed   Ω ={H,T} Where H=head, T=tail.   Event: The collection of all outcomes favorable to phenomenon is called an event. It is denoted by capital letters A,B,C.. Example: Event A is containing at least one head,if two coins are tossed.   Ω ={HH,HT,TH,TT} A={HH,HT,TH} (1) Elementary event: An event containing only one element is called as elementary or simple event. Example: Event A is getting both heads ,if two coins are tossed.   Ω ={HH,HT,TH,TT} A={HH} (2) Compound event: An event which contains more then one sample point of sample space is called a compound event. Example: Event A is containing both head and tail,if two coins are tossed. Ω ={HH,HT,TH,TT} A={HT,TH} (3)Sure event or certain event: An event containing all the points of sample space is called sure event. Example:  In an exp...
