Importance of normally distributed population in data analysis?

The importance of having a normally distributed population is that it makes the calculation of the important aspects of the data set like the mean, variance, standard deviation and other aspects to be easier and more workable. Perhaps it enables the calculation of the central tendency which is an important aspect in data analysis. It helps in the in the calculation of the median, mode and the mean. Therefore, a normally distributed data will prevent one from making the wrong conclusion about a population.

Determine whether this population of daily hires is normally distributed or not?

The maximum daily hire is 63,732 while the minimum daily hire is 3,593. The range between the two values is two high and therefore meaning that the data is much distributed, perhaps it may fail to be normally distributed. Daily number of hires is difficult to predict, because it can either be high, low or average.

The distribution of the data is not normally distributed since the bars in one side are not actually the mirror image of the other side. The histogram fails to form a symmetric shape and therefore don’t meet the required shape to be considered normally distributed but rather forms a comb distribution, since the bars are in alternation of tall and short bars. It therefore means that the mean, mode and the standard deviation for the sample are not equal.

How do the mean and SD change with sample size?

The mean and the standard deviation are changing as the sample size get changed. It basically means that the number of higher over the given period is not normally distributed. The number of higher per day is not that equivalent to the mean, but rather above or below the mean number.

The mean forms the basis of the number of hires that take place over the period that the data was collected.

The standard deviation in this case is a large value; it means that the numbers of bikes that are hired on a daily basis are far away from the mean average of hires over the given period. It means that the data number of bikes that were hired on a daily basis were highly distributed, meaning that they were not concentrated on a specific number per day.
