Question
Analyze your distribution. What shape does your data take? Is it uniform? Is it normal? Describe the shape. If your data looks like a normal distribution, come up with an equation of a normal distribution that fits your data (using the mean and std. dev.)

If all the bars in the histogram are of equal shape then it's uniform.if it's a symmetric with mode in the middle and it looks like a bell shaped distribution then it is a normal distribution.
If a normal distribution is to be fitted then we estimate the mean and variance by the sample mean and sample variance respectively.
