Data Analysis Methods

The selection of data analysis method is an important aspect to achieve the research aim an objectives successfully. There are several methods, which could be used by a researcher to analyze the data obtained through the different data collection methods.

The use of SPSS tools, statistical analysis, thematic analysis, text analysis is some of the methods that are used as per the needs and demand of the research objectives and research data. It is the aspect, which requires an in-depth understanding and consideration over the methods as it is the base to provide findings of the research. Each method of data analysis presents the data in different way, which could raise the different interpretation for same data. It would reduce the ability of researcher to explore the research problem significantly.

Use of SPSS tools helps the researcher to present the findings in quantitative manner, which increases understanding about the research results. The use of this method requires more information from the quantitative methods. On the other hand, use of thematic analysis method to analyze data requires fewer amounts of quantitative data in the comparison of SPSS method. In this method, themes are presented to analyze the pre and post research conditions, which help to determine what exactly is achieved from the study.

The text analysis is the simplest form of data analysis, which is beneficial for the qualitative researches. It presents the data in the form of graphs and tables, which is significant to improve the research effectiveness and reliability.

Value of Physics in daily life

Physics deals with the study of inanimate objects and their behaviour. Objects are inanimate things, and they can have motion and states. Physics studies different aspects of matter like its motion through space, the time taken, the energy, and force it takes to move. Thus the study of physics involves analyzing the matter and understanding the behaviour of world and universe.

It is one of the most important streams of science which plays an important role in our daily life. The tools, machinery, and instruments that we use in daily life are governed by principles of physics. The working principles of all gadgets used by us like mobile, computer, bicycles, cars, etc are governed by various laws of physics.
Another usual example of application of physics in our daily life is electricity and electrical circuits. The law of Newton is very useful to walk, and run. The concept of friction is always counted to load the packages. Physics is also applied to the human body. The electrical signals are exchanged between the neurons, which help to understand the stream of biology, called neurology.

The other most common example of day to day physics is dealing with pressure. When vegetables are cooked in a pressure cooker, the air gets compressed in a small vessel and the out burst (whistle) is the result of pressure created in cooker. When a sealed cold drink bottle is opened, the cork of the bottle pop or fly, it is because of the pressure inside the bottle. .

The laws of physics dissertation help to understand the behavior of liquids. Liquids change their phase on heating and cooling. When water is heated continuously in a pan having a lid, it evaporates at its boiling point and soon the covered lid falls open because steam could not escape and exerts pressure on lid.

There are several other laws of physics, which make our life easier and convenient. They explain the cause and remedies and things to be understandable.
