  7. 7. 7 SIZE AND GROWTH This research institute is big and has been steadily growing. During the time period that sample data collected there were five locations of the company. Those are Colombo, Gampaha, Kaluthara, Kandy and Galle. Graph 1 below shows the number of men and women working at year 2010 in each location of the institute. Figure 01 Number of Male and Female Employees by Location, 2010 According to the Figure 01 during the time period through 2010 the number employees in research institute worked five different locations. From those employees most of the employees were male and that were 79%. Female workers were 21%. Most of the workers worked to the Galle branch and that were 53%. Kandy and Kaluthara came in to the second place and it was 20%. Gampaha came in to fourth and Colombo was fifth with 4% and 3% respectively. According to the above figure 01 Female workers were less than 20% in the each location. Maximum Female workers worked in the Galle branch and it also less than 15%. The Special pattern that I could observe is, in the Colombo branch there were not any Female employees and kaluthara and kandy had same amount of Male and Female employees. By analyzing above data can assume that largest location is in Galle and smallest one is located in Colombo.

SALARY VARIATIONS I examined whether the pay rate differences between Employees changed over time. The following chart shows the initial differences in salary of all the Employees 2010, Table 03 Minimum, Maximum and Sum of Employments salaries, 2010 N Minimum Maximum Sum Std. Deviation Variance Salary 100 16.20 45.40 3,179.10 6.21497 38.626 Valid N 100 According to the above Table 03 Minimum Salary of the Institute was 16.2. It was young Analyst‘s Salary.

  12. 12. 12 Above Figure 04 point up that Females Salary Scale is slightly larger than Males Salary Scale. According to the above figure 04 highest Salary was 45.4 and it has in use by Female Employee. The lowest Salary is 16.2 has taken by Male Employee. AGE VARIATIONS Below Figure 05 illustrates that the Age differences of Male and Female Employees. Figure 05 Age Differences of Males and Female Employees, 2010 According to the above box plot even though there are slight differences both Male and Females Age distribution is quite similar. Youngest employee was in 21 and oldest employee is in 60. Both Male and Female youngest employees was in 21. Both Male and Female oldest employees was in 60. But median values are different. If consider Female box-plot it has positively skewed distribution has the median off-center and generally to the left. The left hand whisker is short while the right hand whisker is long. It reflects the gradual tailing off of data values to the right. Male one also shows the same pattern.
  13. 13. 13 JOB CHANGING Below table represent that the number of job changes by their Employees. According to the table 05 most of the employees haven’t change their jobs. 70% employees are still doing their first jobs. Only 26% employees have left their first jobs and have joined to the research institute. 4% employees have left their jobs twice and as a third job they have joined to the research institute. By examine this table 05 I can assume that most of the workers have come to the institute without any work experiences. Only 30% employees have come with previous experiences. DISCUSSIONS According to the above analyzed data there are many significant patterns and observing those patterns we can come in to the certain discussions. First figure shows that majority of the employees were Male employees. They were 79% of the total employees. I assume that this institute is favored to appoint Male workers than the Female workers. As well as large number of employees are working at Galle. It seems research Institute’s head office or largest branch is in Galle. By examine employment category most of the employees were Managers. It seems that management roles are the most important activities of the research institute. Sometimes that is the reason to have more managers. Moreover they have taken only few Consultants. May be High consultation fees tend to have few consultants. In this study most of the Male Employees were Managers and it is 29% and it seems that most of the Male workers like to be a Manager. As well as most of the Female employees were Academic staff and it is 7%. It can assume that Table 05 Job changing frequency, 2010 Frequency Percent Valid Percent Cumulative Percent Valid 0 70 70.0 70.0 70.0 1 26 26.0 26.0 96.0 2 4 4.0 4.0 100.0 Total 100 100.0 100.0
  14. 14. 14 female employees like to be an Academic staff member. According to the Figure 03 most of the Male employees had Member membership and most of the Female employees had Fellow membership. On the other hand both Male and Female Graduates were less than the other memberships. It seems that Education level is bit lower of these employees. If we compare Male and Female employees in this institute, Male employee’s education level is higher than the Females. According to the above Table 03 Minimum Salary of the Institute was 16.2. The maximum Salary was 45.4. The institute Spend 3179.10 amount per month as Employments salary. These details illustrates that this research institute spend a large amount of money for their Employees salary. Table 04 illustrate that Average Employments Salary is 31.7910. It shows that this institutes Salary scale is High. According to the job moves table most of the employees (70%) has joined to the institute as their first job and still they work to research institute. These records Illustrates that Institute’s employees have satisfied about their jobs. More over the institute also like to appoint fresh employees than taking experience employees because they have appointed more freshers than experience employees. According to the above all the analysis I can assume that this research institute is big and has been steadily growing. Employees also have satisfied about their jobs. SUMMARY In this report, have been analyzed particular data which collected from the employees of the research institute. Those data has been collected through the questionnaires. Those data has been analyzed graphically as well as numerically. According to the given data large numbers of employees were working at Galle branch. If we compare Male employees (79) were larger than the Female Employees (21). Most of the Employees were Managers (33) and less number of employees was Consultants (17). Those data illustrate that graduates (23) are less than the members (38) and fellows (39). According to the Table 03 Minimum Salary of the Institute was 16.2. The maximum Salary was 45.4 and the Average Employments Salary is 31.7910. The institute Spend 3179.10 amount per month as Employments salary.
