Data Collection Data Collection is an important aspect of any type of research study. Inaccurate data collection can impact the results of a study and ultimately lead to invalid results. Data collection methods for impact evaluation vary along a continuum. At the one end of this continuum are quantatative methods and at the other end of the continuum are Qualitative methods for data collection . Quantitative and Qualitative Data collection methods The Quantitative data collection methods

DATA SECURITY IN LOCAL NETWORK USING DISTRIBUTED FIREWALLS ABSTRACT Computers and Networking have become inseparable by now. A number of confidential transactions occur every second and today computers are used mostly for transmission rather than processing of data. So Network Security is needed to prevent hacking of data and to provide authenticated data transfer. Network Security

Data Collection Methods. Introduction Data collection is the process of gathering and measuring information on variables of interest‚ in an established systematic fashion that enables one to answer stated research questions‚ test hypotheses‚ and evaluate outcomes. Data Collection Techniques include the following: Personal Interviews Conducting personal interviews is probably the best method of data collection to gain first hand information. It is however‚ unsuitable in cases where there are

Data Collection and Analysis The research project chosen was the comparison of the 12 ounce cans of Pepsi and Coke. The research team of five‚ individually purchased and tested 3 cans each of Pepsi and Coke. Enclosed below will be the procedure which was followed to obtain the data. The methodology used to measure the liquid was changed to accommodate the way that the tools recorded the measurements. The implications of the changes will be discussed to show that the integrity of the process was
