Question: Generate 100 random number between 50 and 140 by using the following link
https://stattrek.com/statistics/random-number-generator.aspx#error
Present the above numerical data into organized form by using the following methods of
descriptive statistics.
* List of data in ascending order
● Grouped frequency distribution.
● Stem and Leaf Display.
● Histogram.
● Frequency cure, Frequency polygon and Cumulative frequency polygon.
Find the central value of the above data by the following methods.
● Arithmetic Mean (from actual data, grouped frequency data, compare the result
of these two methods)
● Geometric Mean (grouped frequency data)
● Harmonic Mean (grouped frequency data)
● Median (grouped frequency data)
● Mode (grouped frequency data)
● Quantiles (grouped frequency data).

Definition Definition Measure of central tendency that is the value that occurs most frequently in a data set. A data set may have more than one mode if multiple categories repeat an equal number of times. For example, in a data set with five item—3, 5, 5, 29, 473—the mode is 5 because it occurs twice and no other value occurs more than once. On a histogram or bar chart, the element with the highest bar represents the mode. Therefore, the mode is sometimes considered the most popular option. The mode is useful for nominal or categorical data (e.g., the most common color car that users purchase), but it is problematic for continuous data because it is more likely not to have any value that is more frequent than the other.
