About Quantiative Research
Quantitative research consists of information expressed in numbers, variables, and percentages. It seeks to confirm that all problems, dilemmas, or hypotheses have clear, concrete, and objective solutions that can be expressed in a numerical format. This type of research focuses on specific, narrow questions in a double-blind study, usually with a large random group and variables. The data collected can be analyzed with the help of statistics in an unbiased manner with the objective to explain, describe, or predict.

Quantitative research consist of following elements
- a hypothesis
- a random or specific study group with a common similarity
- variables (any element or behavior that can affect or change the outcomes of a study, such as a medication, treatment, or nursing intervention)
- outcomes.
Quantitative research is usually conducted in a controlled environment, such as a lab or healthcare unit. It can be categorized as follows.
3 Types of Quantitative Research
Correlational research is the methodical investigation of relationships or interactions between two or more variables without determining the cause-and-effect relationship the variables may have on each other. An example is studying two chemotherapy medications for compatibility without studying how the medications can have adverse interactions with food or other common medications.
Quasi-experimental research explores a cause-and-effect relationship among variables. It also evaluates the underlying cause of a problem and studies the effects of variables (such as a nursing intervention) to evaluate their effect on the problem.
Descriptive research offers an accurate representation of the characteristics of a particular individual, situation, or group. Descriptive research is a way of discovering new meaning, describing numerically something that currently exists, determining the frequency with which something occurs, and categorizing information.

Contributors: Ruth Belling, Michelle Butler, Catherine Comiskey, Siobhan Corrigan, Gloria Crispino, Orla Dempsey, Suzanne Guerin, Maree Johnson, Carmel Kelly, Elaine Lehane, Maria Lohan, Susan McLaren, Deirdre Mongan, Corina Naughton, Rhona O'Connell, Elaine Pierce, Gary Rolfe, Eileen Savage, Anne Scott, Emma Stokes, Roger Watson ""Learning quantitative research is taken much for granted. This is probably why there are fewer generic books on quantitative than qualitative research. This book is long overdue. Clearly- written and well structured, it takes us through the whole journey of a research project from developing 'research questions' to 'presenting the findings', passing through philosophical underpinnings, recruitment of participants and ethical considerations. Written by an array of well-known researchers and teachers, this book will certainly appeal to new as well as seasoned researchers. Those who will use it, will not be disappointed." Kader Parahoo, University of Ulster "The title of this text is somewhat misleading. It is not only an excellent and thorough guide to quantitative health research methods; it is also an excellent introduction to all forms of quantitative research. It takes the reader gently through theoretical and ethical concerns to the practicalities and benefits of utilising quantitative approaches. As such it is that rare thing; a text that can be used by novice researchers to learn their craft, and a key reference resource for experienced research practitioners." Dr. John Cullen, School of Business, National University of Ireland, Maynooth, UK "This is a first-rate collection of essays that promotes an informed understanding of both underpinning principles and widely used techniques. A great deal of effort has clearly been invested in co-ordinating the contributions, and this has delivered clarity, complementarity and effective coverage. This is a welcome, carefully-crafted and very accessible resource that will appeal to students and researchers in healthcare and beyond." Martin Beirne, Professor of Management and Organizational Behaviour, University of Glasgow, Adam Smith Business School, UK
