Q
Which one is Uniform Distribution Method graph
ANS
A = WEIGHTED AVERAGE BETA DISTRIBUTION
B = NORMAL DISTRIBUTION
C = UNIFORM DISTRIBUTION
D = TRIANGULAR DISTRIBUTION
A = WEIGHTED AVERAGE BETA DISTRIBUTION
B = NORMAL DISTRIBUTION
C = UNIFORM DISTRIBUTION
D = TRIANGULAR DISTRIBUTION
Why
bell shape of normal distribution curve:
NORMAL DISTRIBUTION
To know how bell shape curve formed?
Will explain this example:
you are checking 1000 tests given by pmp aspirants.
your standard value of profeciency is suppose 150 out of 200
this standard value 150 will be called as MEAN value.
now you observe that --- some students are performing better than this , some are below this.
then you make a table of marks at X axis against frequency of students obtaining that marks at Y axis
there are many cases where the data tends to be around a central value with no bias left or right, and it gets close to a "Normal Distribution" like this:

Values = Marks at X axis

Frequency =Nos of students at Y axis
