Data Collection There are two type of data collection, primary and secondary. To begin and start out a research, on a certain subject, we would need to collect data from carrying out from a research. Like said in the beginning, data collection comes in two different form, primary and secondary. The one that is being used is primary source, which is data collected by first-hand knowledge of that person, or when data is collected from a first-hand witness. Some examples of primary data source are focus groups, questionnaires, and surveys. Along with surveys, there are many types of surveys that can be used in different way that could have both disadvantages and advantages. Surveys todays are easy to develop, mainly because of the use of survey software, and the technology today. With the technology today, a lot of people have phone, guiding researchers to do mobile surveys, which is surveys administrated throughout mobile devices. Mobile surveys are helpful because nowadays it seems like almost everyone has a phone, that its relatively easy is administer, it also can boost survey response rate as people complete the surveys without a computer, it can be very easy access to people wherever they may be, and it is less time consuming. But there are also disadvantages to mobile surveys, which include, mobile devices aren’t suitable for lengthy surveys, open-ended questions are harder to answer on a mobile device, it harder to reach older people who may not have smart phones to administer the survey, and currently, mobile surveys are said to be the most expensive surveys to administer. Another popular type of surveys is online surveys, which is mostly use today. It consists of a series of questions that is given online, usually with a survey program. Online surveys can be both good and bad. It can be helpful with the fact that it is also easy to administer, less time consuming, it has greater design flexibility, and there in no interviewer since some people may be more willing to share personal information, and not be affected by the interview. But the cons of online surveys is that there could be a malfunction and could effected the results. Also data errors due to question non-responses may exist, meaning that the number of people who answer differs from the number of people who didn’t answer, creating a bias. Also there is a telephone survey, which is conducted via telephone where potential respondents are called by an interviewer or an automated person to answer questions. Again, there are advantages and disadvantages with surveys. Some advantages to this is that it provides more random and accurate results, it is usually quicker, since you get the results right then and there, and it’s more adaptable, meaning a responder can guide a responder through a question, if they aren’t able to understand it. Some disadvantages to this is that if the survey is given out during working hours, not everyone will be home and also since with the technology today, not a lot of people still have landlines. Other disadvantages could be that the survey could be too long, causing people to drop out on the survey, leaving part of the survey unanswered, and since those responding cannot see or read the questions, complicated or long questions are not that appropriate to be used for telephone surveys. Another type of popular survey is mail survey. Advantage to this is that it typically cost less; they offer a low level of intrusiveness from the respondent's perspective, and most mail surveys do not require a large staff. The main disadvantage of this could be the fact that many mailed surveys are never returned, making the sample very self-selective and less random, since there is little control over who completes and returns the survey and who does not, and it also very time consuming because researchers would need to wait for the results rather than getting it right away. In a face-to-face survey, the interview is physically present in person
