Human Resource Managemnt

Introduction: the data sample used for this study is concerned with work satisfaction, effective management, working condition and stress in work place for the 30 workers of a company. This 30 sample were selected randomly from the given 310 work survey data. Throughout this study researcher will use these 30 data to carry out some of the statistical calculations and statistical graphs for this company’s two branches and its two departments.

This study will also perform a t test to find out whether is there any difference for the effective management of the two branches London and Birmingham. The relation between working condition and work satisfaction will also be investigated.

Task: 1: sampling: in sampling the data used in this research researcher uses the simple random sampling method of random sampling. There are two main types of sampling being used in statistics random or probability sampling and non random or non probability sampling. In simple random sampling every member (unit) of the population (data) has the same probability of being picked for a research, but a member (unit) has no control to be selected for this research because this type of sampling is depends on the discretion of the researchers. (Singh and Mangat, 1996) but the selection of a data has no control, more specifically influences on selection of the others (Black, 2011).

The copy of 30 randomly picked numbers and 30 sample used in this study can be obtained in the appendix 1 and 2.

Task: 2: statistical graphs and calculations:

Mean, median and standard division:

Formulae used:

Frequency distribution and mean, median and standard deviation:

Frequency distribution: frequency distribution is a powerful way of grouping data presented in the form of frequencies and class intervals (Kirch, 2008).

The frequency distribution shown below refers to the work satisfaction of the 30 workers of a company.

Formulae used:

Frequency distribution for working condition:...
