Research questions are specific questions that the researcher wants to know about the intent of study. Polit & Beck (2012) report that the research questions direct the data to be collected for the study. An essential to writing a clear, specific question can be described by the acronym PICO (population, intervention, comparison, and outcome). Typically research questions are developed in a present tense and tend to be interrogative in nature.

But other researchers see evidence for prokaryotic cells in the first 100 million years, maybe even immediately. "...Actual cells have been found in the earth's oldest unmetamorphosed sediments...," says Gould in . Bada says that cyanobacteria may have emerged only ten million years after the first precellular life . In November, 1996, S. J. Mojzsis of the Scripps institution of Oceanography and others reported isotopic evidence that cellular metabolism was under way before 3.8 billion years ago . Even before the research by Mojzsis , Francis Crick was worried by the time problem. "...The real fossil record suggests that our present form of protein based life was already in existence 3.6 billion years ago.... This leaves an astonishingly short time to get life started" . Another researcher, Yale biochemist Peter B. Moore, says this about the time problem :

Scientific method is a well documented, carefully controlled experiment that applies logic, order, and critical thinking skills to solving problems and finding new information.

Your lab report should probably be based around one or two central research questions (RQs). To start off with, caste a wide net and generate at least half a dozen possible RQs. You may want to write down all the variables in the study.

In educational research, we start with a problem area• what is the problem or issue

The first step in hypothesis testing is to set a research hypothesis. In Sarah and Mike's study, the aim is to examine the effect that two different teaching methods – providing both lectures and seminar classes (Sarah), and providing lectures by themselves (Mike) – had on the performance of Sarah's 50 students and Mike's 50 students. More specifically, they want to determine whether performance is different between the two different teaching methods. Whilst Mike is skeptical about the effectiveness of seminars, Sarah clearly believes that giving seminars in addition to lectures helps her students do better than those in Mike's class. This leads to the following research hypothesis:

Two statistics lecturers, Sarah and Mike, think that they use the best method to teach their students. Each lecturer has 50 statistics students who are studying a graduate degree in management. In Sarah's class, students have to attend one lecture and one seminar class every week, whilst in Mike's class students only have to attend one lecture. Sarah thinks that seminars, in addition to lectures, are an important teaching method in statistics, whilst Mike believes that lectures are sufficient by themselves and thinks that students are better off solving problems by themselves in their own time. This is the first year that Sarah has given seminars, but since they take up a lot of her time, she wants to make sure that she is not wasting her time and that seminars improve her students' performance.

Nursing research is essential for all nurses to understand and to practice evidence based nursing in their practice setting. Research is a systematic process. One of the first steps in research is identifying a topic. Think about this...your on a busy medical-surgical floor, as charge nurse you have been given another admit. This admit has increased your nurses (already short-staff) workload. Short staffing has been a consistent problem to your floor. Mistakes have been avoided and made. Would this be a topic for you to refine and develop into a research problem and purpose? First what is a research problem?


This web quest provides an introduction to the research problem and purpose, questions, and hypothesis that are used to direct nursing studies. A research problem is considered a situation directed to create or enhance knowledge, develop solutions, or vast improvement for the practice setting. The research problem may point out a difference between the traditional method and the new finding (the why).A research purpose is clearly written to inform the readers of the intent of study(the what).Research questions guide the study and are interrogative statements that are addressed to answer the main problem.A hypothesis is a predicted statement of two or more variables. Can be analyzed statistically for significance.

In statistics terminology, the students in the study are the sample and the larger group they represent (i.e., all statistics students on a graduate management degree) is called the population. Given that the sample of statistics students in the study are representative of a larger population of statistics students, you can use hypothesis testing to understand whether any differences or effects discovered in the study exist in the population. In layman's terms, hypothesis testing is used to establish whether a research hypothesis extends beyond those individuals examined in a single study.

A research problem in nursing is considered a professional situation in need of improvement, change, or a solution. Polit & Beck (2012) ascertain that both qualitative and quantitative researchers identify research problems by gathering pertinent information on the area of interest. Houser (2012) supports the traditional methods for accumulating relevant information suggests a deductive process (sequential from general-to-specific) or inductive process (specific observation-to-general focus). The research problem statement is considered to be the "why" (Houser, 2012).
