Collecting Collecting is the information process that involves deciding what to collect, locating it and collecting it. It involves more than simply entering data. Collecting involves four steps: • Defining the required data—deciding what data is needed • Identifying the source of the data—where the data can be found • Determining how the data will be gathered—what tools will be required • Gathering the data—collecting and entering the data into the information system. Data can come from either primary or secondary sources. Primary sources refers to data that is collected firsthand. Many organisations prefer to generate their own primary data because they consider it meaningful and reliable, although it is timeconsuming and costly. Data from primary sources is acquired by interviewing people, conducting surveys and questionnaires, or observing a system in operation (see Figure 1.8). Secondary sources refers to data that is collected or created by someone else. For example, newspapers, books, other print media, electronic databases, CDROMs and the Internet are secondary sources. This is often the quickest and least costly method of collecting data. Data is entered into an information system either manually or electronically. Manual entry involves typing the data using a keyboard.
Electronic entry involves entering the data using input devices such as scanners, digital cameras, microphones or sensors. It is important that procedures are in place to ensure the data is accurate, uptodate, relevant and secure. If the data collected comes from unreliable sources or is inaccurate, the information gained from it will be incorrect. This is referred to as
‘garbage in, garbage out’ (GIGO). Organising Organising is the process that arranges, represents and formats data for use by other information processes. It is carried out after the data is collected. The organisation of data depends on the purpose of the information system. For example, if the information system is used to store and search a large amount of data, the data needs to be categorised. This will allow it to be stored in a database. Organising gives some structure to the data. When developing an information system it is essential to determine the format in which the data will be represented. The format of the data determines the most appropriate software application and the processing that can be carried out. For example, if a text document is scanned and represented as an image, the text cannot then be processed using a word processor. If data is poorly organised, it may result in the use of inappropriate applications or the proces sing of unnecessary data.
Analysing Analysing is the process that interprets data, transforming it into information. It involves examining data and giving meaning to it. When data has been ordered and given some meaning by people, it is called information. The particular type of analysis depends on the format of the data and the information that is required. For example, to obtain a report on all the sales in the past month would involve searching, selecting and sorting data. Charts and graphs are often used in the analysis of data. They make it easy to interpret data by making instant comparisons and revealing trends. Charts help people to make quick and accurate decisions. Analysing data may involve the use of a model to represent some aspect of the real world. When a model is used to simulate a real situation, people can make predictions and examine the effect
Process In what way are the data collection procedures appropriate procedures for this study? The data collection procedures such as quantitative data collection are one procedure for the study. Quantitative data collection includes random sampling. This is when a group set of individuals with different characteristics. The hypothesis then has to be answered; this type of data collection focuses on experiments and observations. All data gathered during a quantitative data collection can be used…
and How is the Quality Of Research Data Collection Assured and Checked?” As co-investigator on the well-known and widely used rating scales, he was being phoned by a man hired by the pharmaceutical company sponsoring the trial. The man proceeded to ask him questions like, “Why did you rate this item this way’, ‘Did you consider the influence of this or that’, ‘What was the clinical context of your decision about this score’. Balon began to think about the data that he neglected to think about when…
quasi-experimental design. * The data collection plan. What data collection method—i.e., focus group, telephone interview, observation, secondary data, etc—would you use? What sources of data/information would you use? If you would use an interview, questionnaire, or focus group, give an example of a few of the questions you would ask. If you would use observation, describe and give an example of what the recording instrument would look like. If you would use secondary data, describe the source and specific…
CMGT/441 Introduction to Information Systems Management In light of the recent news story about the phone data collection effort by the National Security Agency (NSA), the right to privacy and government is at the forefront of many minds. FAQ: What the NSA Phone Snooping Uproar is All About written by Jaikumar Vijayan (2013) provides the details and concerns with the NSA’s secret data collection. The topic of privacy is evaluated for the level of importance in relation to the programs used to identify…

the United States Tina Hendley Professor Curry 08/03/2015 Hcs/465 In what ways were the data collection procedure appropriate for this study? For this study I believe that the data collection was which was in the form of an interview. In this study “ Becoming Teen Parents” Ms. Jones had interview 20 teen girls as well as 20 teen boys all from different areas of life, on why they believe they became teen parents. In what ways were appropriate steps taken to protect the rights of the subjects…

uses an enormous quantify of information to conduct test in the process of service delivery. The data assembled goes to a panel of assessment when deciding the option that will best fit the interest of the population, or the experiment idea in question. The content of this paper will define, and describe the different types of reliability, and validity. In addition display examples of data collection method and instrument used in human services, and managerial research (UOPX, 2013). Types of Reliability…
