Hi well this is my 4th blog, and I will be taking you through what I learned in ABP meaning analysis of business problems, so Doctor Yetunde Anibaba has been reversing some case studies with us I know you’re like what’s case studies or study now let me try to break down what a case study is for you.
In this Summary we are going to talk about the case study we are going to use the handbook of practical program evaluation written by Joseph S holly and Catherine E. First what are case studies in a general sense a case study is like an in-depth an extended example that is used to illustrate a particular argument however in a more academic sense a case study is defined as a method for developing a complete understanding of a process program event or activity so in these terms a case study can be thought about as a way of approaching a research topic.
Case studies can integrate both quantitative and qualitative information and they can do this from a variety of sources but they will tend to focus on qualitative information to give an in-depth picture of the issue being studied and the broader environment as explained case studies can be used for several purposes including defining the questions and hypothesis of a subsequent study presenting a description of an event within its context or establishing A cause and effect relationship there are variety of academic fields from medicine to law to media and communications that use case studies.
Case studies are generally categorized in three ways exploratory descriptive or explanatory.
- Exploratory case study is aimed at defining the questions and hypothesis of the subsequent study for example an exploratory case study might involve the in-depth research and analysis of the way a welfare program is successfully operated in a particular state as a result of this case study and using the results that the researchers put forward other researchers can then use this to conduct further research on how to implement or new or updated welfare programs perhaps in other states
- A descriptive case study presents a complete description of an event within its context this means that the research report will be highly descriptive detailed and emphasize the contextual specificities of the particular example being examined and lastly an explanatory case study focuses on establishing.
Now what is Quantitative data analysis? Quantitative data analysis is one of those things that often strikes fear into students it’s totally understandable quantitative analysis is a complex topic full of daunting lingo like medians modes correlations and regression suddenly it we’re all wishing we’d paid a little more attention in math class now the good news is that while quantitative data analysis is a mammoth topic gaining a working understanding of the basics isn’t that hard even for those of us who avoid numbers and math at all costs in this explanation I will try to break quantitative analysis down into simple light size chunks so you can get comfy with the core concepts and approach your research with confidence. So let’s start with the most basic question what exactly is quantitative data analysis despite being quite a mouthful quantitative data analysis simply means analyzing data that’s numbers based or data that can be easily converted into numbers without losing any meaning for example category based variables like gender ethnicity or native language can all be converted into numbers without losing meaning for example English could equal 1 French could equal 2 and so on this contrast against qualitative data analysis where the focus is on words phrases and expressions that can’t be reduced to numbers.
Now what is Qualitative data analysis? To understand qualitative data analysis, we need to understand qualitative data so let’s take a step back and ask the question what exactly is qualitative data well qualitative data refers to pretty much any data that’s not numbers in other words it’s not stuff that you measure using a fixed scale or complex statistics for mathematics so if it’s not numbers what is it? Words?, you guessed well sometimes yes qualitative data can and often does take the form of interview transcripts documents and open-ended survey responses but it can also involve the interpretation of images and videos in other words qualitative data isn’t just limited to text based data so how’s that different from quantitative data well Simply put qualitative research focuses on words descriptions concepts or ideas while quantitative research focuses on numbers and statistics qualitative research investigates these softer side of things to explore and describe while quantitative research focuses on the hard numbers to measure differences between variables and the relationships between them.
