Analysis of the Work Activities and Abilities

To calculate the mean rating for each question on the survey, manual method and or model can be used. To use the manual method, one must know the number of respondents who selected a particle response, usually, the average function is used in this case. The number of individuals who have selected a rating is first multiplied by the corresponding rating value in the given scale. After that, the results of the calculations are then added then finally divided by the total number of responses to the given survey question. However, in this case, only one respondent is considered. However, the obtained information was analyzed using the SPSS and the following table was obtained.

Descriptive Statistics
	Mean	Std. Deviation	N
Generalized Work Activities	3.3500	1.72520	20
Abilities	2.8000	1.10501	20

From the table above, the mean rating for each question on the survey is 3.35, this mean rating, however, is for the generalized Work Activities. The mean rating for each question on the survey for the Abilities is 2.8

The interrater reliability refers to the degree of agreement among the raters, it simply defines the level of consistency. In order to calculate the interrater reliability, in this case, we obtain the analysis from the SPSS, the interrater reliability is obtained by dividing the number of agreed ratings by the total number of ratings then multiplying by 100%, the interrater reliability can be given in percentage form (…Information Network, 2010.

For instance, in this competition, raters have 3 out of 5 scores. The Percent agreement is 3/5 = 60%.     

The ability’s scales have various scales such as the importance scale which indicate the degree of importance a descriptor or skill is to the occupation under consideration. The ratings on this scale usually run from "Not Important" (1) to "Extremely Important" (5). The level three section of the scale has various domains sch as skills, work activities et cetera. This usually shows the extend to which a descriptor is needed to be able to carryout a certain occupation. The relevance of the scale explains the pat of the jobs that incumbents rated the offered task as being relevant to their job. Furthermore, the frequency usually signifies the number of times a certain task crops up within a given period. The occupational interest usually covers the interest. The extent has a work value domain that indicates the extent to which the occupation is affected by a given item. Moreover, the context has a work context containing various context variables. The precision rule usually applied to an occupation that was not available. However, the relevance od a task is signified by is percent relevance, such that a task is relevance if I have a general percentage of equal to or greater than 67%. In addition, that, the mean importance of a task according to the analysis indicated to be 3.35 hence a task is important if its results equal or surpasses this value. In the tsk category, there are those tasks which are less relevant, or they are actually not that much important to the occupation, in such a case, therefore, they are rated at ≥67% and <3.35 or rated to be <67% assuming the mean importance.

The statistical findings are obtained from SPSS and the tables show the various statistical findings.

Coefficientsa
Model	Unstandardized Coefficients	Standardized Coefficients	t	Sig.
	B	Std. Error	Beta
1	(Constant)	1.009	.932		1.082	.294
	Abilities	.836	.311	.536	2.691	.015
a. Dependent Variable: Generalized Work Activities

The data collected were analyzed by the SPSS and various output were obtained. In the table above, the coefficients of analysis are shown. In this regard, the Abilities were the independent variables while the working generalized work activities were the dependent variable. Linking the two with a regression line equation, we obtain a regression equation like: Y=a + bX, the values of a= 1.009, b= 0.836, the equation then becomes Y=1.009+ 0.836X which can be written as: Work Activities=1.009 + 0.836 (Abilities). This implies that the work activities are likely influenced by the Abilities and the higher the abilities an individual has, the better he/she would perform the work activities.

Model Summary
Model	R	R Square	Adjusted R Square	Std. Error of the Estimate
1	.536a	.287	.247	1.49680
a. Predictors: (Constant), Abilities

From this table, the value of R=0.536, this value shows a positive linear correlation between the Generalized work activities and the Abilities, however, the relation is moderately positive. The value of R2=0.287, this value is too low, and it implies that only 28.7 of the data can be explained by the model.
