Title: Unemployment rate (aged 16 and over, seasonally adjusted)
Introduction:
 This study is based on the unemployment rate, age 16 and above. The data has been
selected from the sources of LMS during the period of 1971 to 2019. The data in the above
study are given in yearly, quarterly and monthly basis. The descriptive statistics and
graphical representation has been included in this study.
 Now a day’s unemployment is a burning problem in a society or country (Draghi 2014).
The term unemployment is used to define the percentage of unemployed people as
correspond to total number of working people or working labor force. The main aim of this
study is to illustrate and analyses about the fluctuation of the current and 1971 period rate
of unemployment. Moreover to determine the improvement on rate of employment is other
aim of this study (Desilver 2013). The calculation of this study has been conducted in the
MS-Excel. In the calculation part descriptive statistics, bar chart, histogram, pie chart has
been shown.
Literature Review (Main body):
 The study on the unemployment rate, age 16 and above is a single variable study, since it is
a single variable study so the method of descriptive or summary statistics is the best and
appropriate method in this situation. Moreover in the graphical representation part
histogram, bar and pie chart has been included.
Table 1 Summary Statistics on Unemployment rate (yearly basis)
Source: (As created by Author)
Table 1 shows the descriptive or summary statistics on unemployment rate during 1971-
2019. The mean or average unemployment rate during this period is 6.894%. The median or the
second quartile value on unemployment rate during 1971-21019 (yearly basis) is 6.2%. Similarly
the mode or the highest number of observations occurred in this period is 5.4%. It is clear from this
table that the mean value of this unemployment rate is larger than the median. Hence the rate of
unemployment is right or positively skewed. The value of the skewness is 0.594%. In this study
there are 49 observations has been included. The minimum rate of unemployment rate is 3.7% and
2

the maximum rate is 11.8% Hence the range of this variable is 8.1%. The variability on the rate of
rate of unemployment during the period of 1971 to 2019 is 5.636%.
Table 2 Frequency Distribution on Unemployment rate (Yearly basis)

Table 2 shows the frequency distribution on the rate of unemployment during the
period of 1971 to 2019 (yearly basis). In this table the first column shows the class. There
are 5 classes has been included with the length of the interval is 2%. The second shows the
upper limit of this interval. The third column is the frequency column. The frequency
column defines that how many observations has been occurred in the above interval. The
next column is the relative frequency. The relative frequency has been calculated by the
ratio of the given frequency and the total frequency. Similarly the last column shows the
cumulative frequency, which has been calculated by sum of frequency up to the cell
frequency in the given period. From this table it has been cleared that the maximum number
of unemployment rate has been occurred in class of 4% to 6%. The number of observations
in this class is 21. Similarly the minimum number of observations has been occurred in the
class of 2% to 4%. The number of frequency in this class is 3.

Figure 1 Histogram on Unemployment rate (Yearly basis)

Figure 1 shows the histogram on rate of unemployment during the period 1971 to
2019 (yearly basis). In this histogram in the X-axis represent the class and the Y- axis
represent the frequency. It has been seen from this histogram that the maximum number of
observations has been occurred in the class of 4% to 6% and the value of the frequency is
more than 20. Similarly the minimum number of observations has been occurred in the
class of 2% to 4% and the value of the frequency is less than 5. Moreover it is also clear
from this histogram that the data has been skewed positively during the period of 1971 to
