Tools used in research. Tools used in the research is that the researchers chose to use or to use in the collection of data in research. Tools used in research there are many kinds of each type has different characteristics and properties. Is suitable for each type of storage is not the same. Researchers must have the knowledge and expertise in the use of each type of tool to get the correct information as fact. Tools used in research must have a reliable quality. This has to be the quality. Poise and power breakdown. A straight is a property of a measuring tool, what is needed is divided into 3 categories of content to meet the criterion in relation. This type of tool. 1. a measuring instrument to the physiology as existing tools such as scales, blood pressure. Measuring height Timer clock The measuring machine thoemomitoe, etc. 2. Tools of social psychology as a tool for both existing and newly built. Where these tools will have different features and is suitable for each type of information is collected are not the same. Therefore researchers must understand enough about the various tools and techniques as well. These tools include: 2.1 the questionnaire (Questionnaire) refers to a series of questions that the researchers provided respondents who provided information directly. Write the answer in any one or more of the subject matter that researchers are interested in education, such as resumes, attention, attitude, feeling, or idea to the fact some of the most popular queries on social science research hassle-saving because of the complex, but the creator must have knowledge and commemoration.The experience to complete the questionnaire, the received quality. Select the use the query in any format. Want to discover how data analysis information and samples using study questionnaires that should be easy to answer. In response, and data analysis. The number of questions, not too much or too little. Queries with multiple features, such as custom answers (Check list), and the estimated value (Rating scale) The process of creating a query1. define the purpose and scope of content 2. define the characteristics of the questions on the scope, content and purpose. 3. the draft questionnaire. 4. check and adjust the correction (by an expert) 5. bring to trial (Try out) 6. improvement. 7. practical implementation Advantages of questionnaires. 1. saves time, expense 2. the respondents are free to respond. 3. in the case of collect information from large numbers of samples. 4. There is evidence of written information stored check. 5. you don't need an expert to collect the data. 6. can control the query to the recipients in a similar time. The constraints of the query. 1. always have the query returned at least one of. 2. the respondent did not answer yourself. 3. applicable scope limited to only write out readers. 4. the respondents may not understand, do not reply or respond to the aim of question. Answers do not match. The truth. 5. unable to observe the reaction of the respondents. 6. If there are a lot of questions, respondents may be bored and respond, not only to the previous answers that match reality. 2.2 the interview. The interview is a way to find information by chatting with aim. Define objective beforehand as a way to get that information into the information required to fulfil. How is the interview method used in most research support comes from using a query? The interview is generally divided into two questions, property characteristics: 2.2.1 interview with scheme or the exact structure. In case of need the answers as set only. Consequence, just closed at the end of the query type, but used interviews and instead meet the precision structure is a property of the tools to measure things like whether a measure is a constant. An precision value, there are several ways to test, how to find a constant inside and how to find the poise of the observation. Authorities classified the properties of a tool that can extract the data of people who are feeling think differently from each other. By the calculation of the proportion, or find one at a time (t-test) A good tool must have the following qualifications: be a precision direct ponnai. Sensitive high resolution power test so that it can be used easily and effectively (examples research. online: 2557 (2014)) A simple random sample group. A simple random sample (Simple Random Sampling) is that a random Member. All the units of a population that has not yet had a chance to equally and independently to.It is suitable for use with the sample population with similar conditions. Breakdown is as follows: 1. a random sample by way of lottery (Lottery) is a sampling.From a population that has very little, and a little (Koul, 1984: 108) with step by step. Operation. As follows: 1) identification number is assigned to all members of the units in the population. 2) na Member's identification number is provided as the label. 3) lottery numbers come up one at a time, until the number of samples.That must have been captured by the label will have to be put back to a random population of old. As a result ofAchieve equality in obtaining a random sample, but if you don't put a night to make a group.An example is more likely in a random. 2 a random sample by random number table help (Table of Random. Numbers) is a large sampling using random number tables set up on the computer. Do not make the lottery. There are action steps. As follows: 1) identification number is assigned to all members of the units in the population. By taking into consideration the number of samples. As follows: A population of 100 people, numbers 1-100. A population of 500 people, numbered 1-500. A population of 1000 people, numbered 1-1000, etc.Observations of simple sampling (nonglaksa Wirat won, 139: 2543 (2000)) 1) is a method that is used quite a lot because of how simple and. Estimation bias is simple; Do not use the formula optimized when using random other ways. 2) why do not how to.
