1. Know the Type of
Data You Have
Before you can select the right analysis method, you'll need
to know how to categorize your data. Generally, data can fall into two broad
classes: qualitative and quantitative, and each of these requires those
different methods of analysis. The nature you understand will then enhance the
process of determining a method of analysis that suits your need.
•Qualitative Data:
This is non-numeric data that is descriptive. Interview, focus group
discussion, open-ended survey, and observational notes are good examples. The
basic idea is that since qualitative data do not involve any numbers, such data
analysis is always devoted to the exploration, interpretation, and
understanding that might underlie patterns and meanings. The analysis process
generally includes categorizing or coding data into emerging themes.
The most common qualitative analysis methods include the
following:
-Thematic analysis is a method of identifying themes or
patterns within the data and categorizing them into overarching themes or
categories.
-Content analysis is a method that involves counting the
frequency of particular concepts or phrases in textual data to reveal patterns.
-Grounded theory is a more elaborate process in which
theories are built from the data itself straight away for securing in-depth,
context-driven comprehension.
• Quantitative Data: Quantitative
data is a numerical observation for subsequent statistical analysis. Usually,
quantitative data are collected by means of surveys, experiments, or different
measurement tools that can be statistically analyzed to test hypotheses,
analyze relationships between the variables, or make inferences about a larger
population.
Some basic methods of quantitative analysis are as follows:
o Descriptive Statistics: These
involve the summarizing and describing of central tendencies and other
important aspects of your dataset, including means, medians, standard
deviations, and frequencies.
o Inferential Statistics: These
techniques allow us to make predictions or inferences about a larger population
based on data from a sample. These include t-tests, ANOVA, correlation
analysis, and regression analysis.
2. Identify Your
Research Objective
Understanding your research purpose is highly influential in
deciding which data analysis method to use. The purpose of your study will
directly impact the methods used for analyzing data.
• Exploratory research: If the
study is one that seeks to explore patterns, themes, or insights without a
specific hypothesis, qualitative may be the way to go. Drawing on thematic
analysis or content analysis may open up avenues for exploring the data with
little preformed notions.
• Explanatory analyses: Should
you wish to explain relationships between variables or test hypotheses, methods
like regression analysis, t-test, and ANOVA would probably be the best courses
of action. These methods will allow you to identify and explain the
cause-and-effect relationships or associations among variables.
• Predictive research: If your
goal is to predict some future outcome or trends based on past historical data,
you can think of utilizing more advanced predictive analytics techniques and
regression modeling.
3. Understanding how your data is measured and organized
consists of its data scale. Very significant, because the data scale will
practically dictate what methods you will be able to use in analysis.
Understanding the scale of measurement will help you choose the right
statistical analysis method.
• Nominal Data: Data that
consists of non-ordered categories (i.e., gender, ethnicity, marital status).
For your nominal data, methods such as Chi-Square Tests or Logistic Regression
would be ideal for studying relationships or associations between categories.
• Ordinal Data: Data in this case
consists of categories with some order but with inconsistent intervals between
categories (i.e., Likert scale responses, rankings). Mann-Whitney U Tests,
Kruskal-Wallis Tests, or Ordinal Logistic Regression are typically used with
ordinal data.
• Interval or Ratio Data:
Continuous data having equal intervals between values that have a true zero
(i.e., temperature, height, weight, income). Interval or ratio data use more
complex methods of analysis, such as t-tests, ANOVA, and Pearson Correlation.
4. Check Assumptions
Related to Various Methods
Before deciding on choosing a data analysis method, it is
useful to check the assumptions under each type of statistical technique. Most
statistical analysis assumes that certain properties are present in the data,
and the analysis would not hold if they were not satisfied.
For instance:
• t-tests and ANOVA assume that the data
is distributed normally. If your data is not normally distributed, you should
use non-parametric tests such as the Mann-Whitney U Test or Kruskal-Wallis
Test.
• For regression analysis, linearity,
multicollinearity, and independence of residuals will check their assumptions.
If violated, these assumptions might affect the results' validity.
It is vital to ensure that the data complies with these
assumptions for deriving meaningful and valid results.
5. Analyze the
Complexity of Your Data
The complexity of your data will affect how you analyze it.
In some studies, large multi-dimensional datasets with many variables are
involved, while in others, the focus is on simpler datasets.
• Where
your objective is to discover the combined effect of several independent
variables on a dependent variable, choose multiple regression analysis or
multivariate analysis.
• Or for
more complex datasets, you may want to use factor analysis or cluster analysis
to reduce the number of variables or find patterns.
• Structural
Equation Modeling (SEM) is a very advanced method that enables you to assess
complex relationships among variables with both direct and indirect effects.
Understanding just how complex your data will assist your
choosing an analysis model to manage the number of variables and relationships
in it.
6. Consider the
Availability of Tools and Resources
While choosing upon the method of analysis, also take into
consideration the tools and software that are at your disposal. Your choice of
software will influence the ease with which certain techniques may be applied
and the reliability of the results obtained.
• SPSS: An extremely versatile
application designed for performing statistical analysis, suitable for basic
and intermediate level research.
• R: Software used for complex
statistical analysis and data visualization for free.
• Python: A programming language that is
best for complicated statistical analysis and related data operations.
• Excel: Excel, though its application is
limited, can be a useful tool for analyzing smaller datasets and for
introductory statistical analysis.
Select the software that's compatible with your comfort
level and research demands and ensure that it accepts the kind of analysis
techniques you would like to employ.
7. Consult An Expert
Choosing the wrong data analysis techniques can be quite
intimidating to students who lack experience in these advanced statistical
techniques. If you are unsure which option to go for, the best thing to do is
to ask an expert.
