Graphical Representation
The distribution of the 200 random numbers is shown in the histogram above. It includes a Kernel Density Estimate (KDE) overlay, which provides a smooth curve representing the distribution.
Interpretation:
-
Mean and Median: The mean is slightly negative at , and the median is nearly zero, indicating that the data is approximately centered around zero, as expected for a standard normal distribution.
-
Standard Deviation: The standard deviation is close to 1 (), consistent with the standard normal distribution's properties.
-
Range: The minimum value is and the maximum is , indicating that the data points are within a typical range for a standard normal distribution (about to ).
-
Distribution Shape: The histogram shows that the data follows a bell-shaped curve, characteristic of a normal distribution. The KDE plot aligns well with the histogram, further confirming the normality of the data.
