Statistical vs. Data Analysis: Key Differences

Statistical Analysis vs Data Analysis: A Comprehensive Guide

Statistical analysis is the process of collection and interpretation that is used to reveal patterns and trends in a large set of data. It can uncover the patterns in a set of data by calculating the data’s mean and median, or you can use hypothesis testing methods such as the chi-square test to assess whether observed patterns differ from the expected patterns. If you are in search of a data analysis expert, we offer personalized statistical and data analysis services for your raw data set. Statistical analysis is crucial because it gives important insights for decision-making and helps make predictions based on past trends.

Data analysis is the use of techniques to make conclusions based on existing data. It is used to gain insights from raw data sets, which are then used to make strategic decisions or come up with ideas for future research. Below are the key steps involved in the data analysis process:

Data Analysis Process

  • Define the research objective
  • Data cleaning.
  • Data collection.
  • Data analysis.
  • Interpretation of the output.
  • Reporting and evaluation.

Difference Between Statistical Analysis and Data Analysis

Statistical analysis differs from data analysis in that statistical analysis applies statistical methods to data sets to understand, while data analysis involves inspecting, cleaning, and modeling existing data into useful conclusions. Data analysis can be used when conducting statistical analysis in that data obtained from various sources can be used to conduct statistical analysis.

Process of Conducting Statistical Analysis in Research

Carrying out statistical analysis in research involves a series of steps. Below is a step-by-step guide with examples of how you can carry out statistical analysis:

Step 1: Write your hypothesis and establish your research question.

The goal of statistical analysis is to answer a research question. This research question is what we call the hypothesis. It guides the research and sets the direction for carrying out the statistical analysis. There are two types of hypotheses: Null hypothesis and alternative hypothesis. The null hypothesis predicts no relation between variables, while the alternative hypothesis states the research prediction. Below is an example of each hypothesis:

  • Null hypothesis- Doing 10 math questions daily will not affect scores in students.
  • Alternative hypothesis- Doing 10 math questions daily will have an effect on math scores in students.

This is an important step as it lays the foundation of a systematic approach to carry out the analysis.

Step 2: Planning your research design

A research design is the plan for how you plan to conduct your research. There are several types of research designs, such as experimental research design, exploratory research design, etc. Below is an example of the experimental research design:

Using the research topic of whether doing 10 math questions daily affects student scores, you take previous scores of the students, then have the students do 10 math questions daily for a designated period then record the scores after.

Step 3: Measure variables

For statistical analysis, it is important to determine the measurement standard for your variables. Variables are measured at different levels of precision. Data can be quantitative or categorical. Quantitative data represents quantity, such as kilometers, while categorical data represents groupings, such as gender. Determining the measure standard is crucial for choosing hypothesis tests.

Step 4: Collecting data from a sample

The next step is collecting data from a sample. One should use a sample that is representing the population. You can use appropriate sampling procedures to apply the research findings beyond your sample. One determines the method of data collection to be used relevant to the research question.

Step 5: Summarize your data using descriptive statistics

After data collection, you summarize the data by calculating the descriptive statistics. The goal of this step is to summarize the data collected and give a clear overview of the output. Descriptive statistics are such as the mean, median, and standard deviation.

Step 6: Testing hypotheses

This step involves applying inferential statistics to test the hypotheses. Inferential statistics involves using a data sample to make predictions of a large population. Depending on the nature of the hypothesis, standard techniques such as t-tests can be used in this process.

Step 7: Interpretation of results.

The final step of this process is interpreting the output. This involves comparing the output with other results of existing research and suggesting other areas for future research.

Why You Need Data Analysis Help

Whether you’re a researcher, professional, or student trying to carry out data analysis, getting help from expert statisticians can be a good idea.
