Top 10 tips for writing a dissertation data analysis
A dissertation is merely but a complicated version of a thesis statement. Whenever writing a dissertation paper, the process entailing data analysis and working with statistics can be complicated at first. This true whether one is using specialized data analysis software such as SPSS or a more descriptive approach; however, there are a few guidelines one can follow to make the process simpler. However, there are a few approaches used in making things simpler.
Never follow blindly the data collected; ensure that your original research objectives determine which set of data does and does not make it into the data analysis. All the presented data needs to be appropriate and relevant to your goals. The irrelevant data will always illustrate a lack of focus and incoherent thought. By informing the reader on the academic perceptive behind your data selection and analysis, this illustrates that one is able to think and get to the core of certain issues critically.
It is essential for you to use methods that are necessary to both the type of data gathered and the research aims. The researcher should be positioned to justify such methods with a similar thoroughness with which the data collection methods are justifiable. Note that you need to constantly convince the reader that the method implemented had not been hazardously chosen, instead arrived at based on critical reasoning and prolonged research.
3. Quantitative Work
Typically, scientific and technical research, and to some cases, sociological and other cases, quantitative work requires statistical analysis. The collected and analyzed quantitative data shall enable the researcher to draw to a generalized conclusion beyond the samples.
4. Qualitative Work
Analyzing qualitative data can be time-consuming, given the process is regarded as iterative, in some cases, requiring the application hermeneutics. It is essential to know that the main goal of utilizing research and the qualitative approach is not to create statistical representative or valid findings but uncover an in-depth, transferable knowledge.
5. Attention to detail
The researcher should thoroughly analyze all the set data aimed at using the support or refute academic positions, demonstrated in all regions a complete engagement and critical perspectives, majorly in reference to the possible biases and mistakes. The researcher should as well be able to acknowledge the necessary limitations as well as the data strengths.
6. Presentation strategies
Given the difficulty in presenting large volumes of data, one needs to firsts consider all the available means of presenting the collected data; this can include charts, quotes, graphs, and formulas. Even though the researcher might find a specific layout to be clear, it is essential to have the reader in mind and consider if they would easily merge with the format implemented.
in a case the researcher finds the data analysis section becoming clustered yet unwilling to reduce the amount of data collected, given its relevancy and difficulty in organizing the data within the text, then you might consider moving the data to the appendix section. In addition, the datasheets, transcripts of interviews, and sample questionnaires should also be placed in the appendix.
In this, one will need to demonstrate a capacity to identify the patterns, trends, and these within the data. The researcher will also consider the numerous theoretical interpretations and balance the cons and pros of the various perspectives. Discuss the consistencies, as well as the anomalies, assessing the importance and impacts of each. Ensure to include representative quotes whenever you are using interviews.
The findings should be precisely stated with their assertions supported with tightly debatable reasoning and empirical backing.
10. Connection with literature
At the end of your data analysis, it is essential to compare the attained data with that which has been published by other scholars, considering the points of difference and agreement, discussing reasons as well as the possible implications.

Data Analysis Techniques
1. Data Visualization:
It has become one of the most demanded methods due to its ease and speed when it comes to interpreting and detecting patterns in the data through infographics and / or graphics, which provide different software today.
2. Split Testing:
Better known as A / B testing, it is a system widely used in digital marketing. It consists of comparing a series of actions and observing the reactions of users to a particular product or message. In this way, differences can be detected to determine what works best and achieve greater conversion.
3. Temporary Series Analysis:
It consists of a set of statistical techniques that analyze sequences of data points to predict the probability of a result. Predictive analytics is set and learned from the past to project certain scenarios in the future, such as, for example, the total sales of a company for the next year.
4. Analysis Of Feelings And Texts:
We talk about analysis techniques that are based on aspects as subjective as our emotions, but that helps to recognize the attitude of a person or group. Text mining does the same but with the semantics of large volumes of texts. Both methods are of great importance for companies
5. Association Rules:
These are algorithms capable of detecting a relationship between different variables in a database. This practice helps to establish rules and / or patterns of customer behavior and to detect.
Most Important Methods for Statistical Data Analysis
- Mean – the sum of listed numbers divided by the number of items on the list. This used to determine the overall trend of the dataset or helps in providing a snapshot of the data.
- Standard deviation – often represented with the Greek letter sigma, is the measure of a spread of data around the mean. In Standard Deviation signifies, the high value determines that the data is spread widely from the mean, and the low value determines that the data aligns with the mean.
- Regression – this models the relationships between dependent and explanatory variables usually charted on a scatterplot. The line of regression also decides whether the relationship is strong or weak. It has a lot of applications in data science.
- Hypothesis testing – In data analysis and statistics, the result of a hypothesis test is considered to be statistically significant if you cannot give the results by random chance. Hypothesis tests are used in everything from science and research to business and economics. You just have to keep a lookout for common errors, like the placebo effect and the Hawthorne effect.
qualitative data analysis
this infers to non-numerical information such as notes, interview transcripts, text documents, audio recordings, images, and notes. This can be divided into the following,
- Narrative analysis – this involves a reformulation of storied presented by respondents taking to account the context of every case and the divergent experiences by every respondent.
- Framework analysis – this an advanced methodology comprising of numerous stages such as identifying the thematic framework, familiarization, charting, coding, interpretation, and mapping.
- Content analysis – this infers to the stages of categorizing the behavioral or verbal data in classifying summarizing and tabulating data.
- Discourse analysis – this an analysis method of naturally occurring talk, including written texts.
- Grounded theory – this a method that commences with single case analysis to formulating a theory. Through which additional cases get examined to confirm whether such contributes to the theory.
quantitative data analysis
the quantitative theory comprises of two routes, including:
- Experimental research – this tests the precision of theory through identifying the independent variables that result in an impact of the dependent variable.
- Descriptive research – this gauges the sample at the moment in time, explaining the demography of the samples.
