This study is based on the internet speed of the National Broadband Network.
According to this study, it has been seen that maximum download speed is 50 Mbps and
maximum upload speed is 20 Mbps. The 120 observations have been selected in this study.
The histogram has been drawn based on speed test 1 download only for evening. In
this histogram in the X-axis shows the class and the Y-axis reflect the frequency. It clear
from the histogram that the data set is symmetric. The maximum number of frequency has
been occupied in the interval 40 to 45, and the frequency is 30. Similarly, the minimum
frequency has been occupied in the interval 30 to 35 and the frequency is 2.
The 46 observations have been selected in the speed test 1 download for evening. The
mean of the speed test 1 download for the evening is 41.98. The median or the second
quartile of this data set is 44. Similarly, the mode of the speed test 1 download for the
evening is 44. It has been seen that the mean of this data set is less than the median. Hence
the skewness of speed test 1 download for the evening is negative. The value of this skewness
is -1.41. The standard deviation of this data is 3.76.
The box plot of different download speeds shows that the data-sheet is symmetric. In
other words, difference download speed data is normally distributed — the value of the
bottom whisker that the difference between the first quartile and minimum is 13.33.
Similarly, the top whisker that is the difference between the maximum and the third quartile
is 12.40.
