selecting units that may be people‚ organizations etc‚ from a larger whole i.e. from a population of interest‚ so that by studying the sample we may come up with general characteristics of the entire population under consideration. Types of sampling methods: Probability sampling Probability sampling is a type of sampling that includes random selection. And in order to achieve random selection‚ it must be made sure that different units of population have equal probability of being chosen

BACKUP METHODS One of the important aspects of data security involves protecting data from loss or destruction. In this short paper‚ I will cover the backup methods we can use to protect our data and reduces the chances of data loss. Popular hardware devices used for making hard drive backups on standalone personal computer or small servers include tape‚ Zip‚ and Jaz drives. In business environment‚ however‚ if a PC is connected to a file server‚ the most practical backup approach

Question: investigate the water potential of potato tissue? Introduction All cells require essential materials to ensure their survival. Chemical‚ physical‚ and biological processes are used to move these materials inside of cells. Similar processes move waste materials outside of cells. These processes can be passive‚ occurring as a result of basic physical laws and requiring no outside energy from the cell or they can be active‚ requiring energy expenditure. Since all molecules possess kinetic

Methods and Procedures The study used experimental and descriptive study type of research. The experimental method was used to prove and test the hypothesis by the use of controlled observations and measurements. The descriptive method was used to describe data rather than explain it. It develops‚ tests and evaluates methods of research. It also explores experience in real life situations. Common methods for gathering data are questionnaire‚ interview and observation. 1.

belief of my own to hold on to. I also discovered that as a young girl I was using the technique called the "pillow method" without realizing that was what I had been doing. Apparently this method was developed by a group of Japanese schoolchildren‚ and gets its names from the fact that a problem has four sides and a middle‚ just like a pillow. An example of when I used the pillow method was when a friend and I were discussing the laws regarding marriage as a legal right via a popular social networking

available. In this analysis‚ the method used to convert the point data into raster format is the inverse distance weighted‚ IDW. It determines cell values using a linearly weighted combination of a set of sample points. The weight is a function of inverse distance. The surface being interpolated should be a variable dependent on location. The IDW interpolation technique was applied as it was found to be more accurate. Ali et al. [32] tested five wind speed interpolation methods (i.e. IDW‚ global polynomial

The Scientific Method Introduction: In performing this experiment‚ students apprehend and grasp the concept of the “scientific method” and its segments. The scientific method is analytically preceded by researchers to answer a question(s). First‚ the analyst states the problem based on contemplations. Next‚ a hypothesis is formed‚ which means the analyst made an educated guess (solution) to the problem. Before an experiment is performed the analyst has to make a prediction. A prediction is what
