 Generally, the researchers are not as simple as the early students of psychology or the beginner researchers would do, but the exam research could involve the researchers which are of higher and secondary level. The secondary research study using identifiable private information or biospecimen is another example for that. Secondary research that uses identifiable private information or identifiable biospecimen is exempt of review if at least one of the following criteria is met. So in certain situations we can see that the secondary level of exam research could be do if we have certain following points to meet the criteria. The first one is that these sources are publicly available. If the sources of some research are publicly available, like the opinion survey of a human participant's opinion survey, we have the data of 3,000 participants available that which party they are going to possibly vote in upcoming election. This is the available data source and this is also called the secondary research study and it is also exam research. Then information is recorded by the investigator in such a manner that participants cannot be identified directly or through identifiers. This is a situation in which someone has contributed to a poll and you are not going to identify that which participants has given the vote in favor of which party. Research is conducted by or on behalf of a federal department or agency using government government generated information obtained for non-research activities. So they could be the different part of organizations like the federal government, the provisional government, the law enforcing agencies, the Gallup surveys, the human and health department surveys who may be going to do this kind of research and in the result of that research it is not always mandatory that you are going to identify the specific participants and its response from the total opinion poll. So whenever we do something of Isra, it is an exam research of the secondary source and it is not possible to identify it from the inside that a common individual, a human subject, what opinion or what opinion he is giving. But this is very important that you can take an opinion of a general public in this manner whereas they don't have any fear that they are going to be judged because of their response. So you know, in this type of situation, your true behavior reflects, your true opinion comes before your survey. Then research projects conducted or supported by federal department or agency. This type of research is also examined if it is designed to study, evaluate, improve or otherwise examine the public benefit or service programs and their procedures. So any research that the government is doing or any special institution is doing, for instance, if a police department has launched a women's safety app and they want to see how many women will use that app or use it to feel protected, then a general survey can be run in which the women's identity will not be revealed but along with that this information will be easily found that how many people are comfortable, can install it or can effectively use it. Taste and food quality and consumer acceptance. This is also a domain in which we do a lot of exam research and this research is very much important especially in nowadays where the food authority department is working very effectively to identify the problems which is involved in different food areas or restaurants or food deliveries or food cake cooking, what problems can be there in its manufacturing. So there exam research is very important to conduct. This research is examined if a food is consumed containing ingredients found to be safe. If you are looking at the quality of food in some research and if a human subject is involved who is eating it, then the exam research will be considered but the ingredients will be necessary to ensure that it is safe. Then food containing agricultural chemicals or environmental contamination at or below level found to be safe. That means there should be no contamination in it. There should be no chemical or agricultural hazardous components and they have to be checked by food and drug administration. Let's let you know if we are doing a formula milk test on the children and it has been approved that there will be no damage to the health of the children, then we can do a growth test on infants who are taking that formula milk as compared to the other children who are not taking formula milk. So the exam research is done but there is no harm involved in any kind of harm involved for infants and children who are participating in it. Similarly, we have different foods that are available in the market and they are approved to be taken by human subjects. If we are doing some research in comparison with them and there is no damage but we are seeing some health benefits, then we can conduct an exam research there as well. So they are the different settings in which we can conduct an exam research but yet we need to see different regulations which should be followed full.
