Data analysis is the process in which data are examined and cleaned, transformed and modeled with the goal of identifying useful information that will aid in making decisions. It can be done using various statistical and analytical techniques that include descriptive analysis (descriptive statistics like frequencies, averages, and proportions) and regression analysis. cluster analysis, and time-series analysis.

To conduct a successful data analysis it is important to begin with a clear research question or objective. This will ensure that the analysis is focused on what’s important and provide valuable insights.

When a clear research question or goal is identified, the next step in data analysis is to collect the required data. This can be done by using internal tools, such as CRM software, business analysis software, internal reports, as well as external sources like questionnaires and surveys.

The data is then cleaned to remove any duplicates, anomalies, or errors. This is referred to as “scrubbing” and can be done either manually or with automated software.

The data is then compiled to be used in the analysis. This can be done by using a graph or table created from a sequence of observations or measurements. These tables may be one-dimensional or two-dimensional, and they can be categorical or numerical. Numerical data may be continuous or discrete. Categorical data can be nominal or ordinal.

The data is then analysed using various statistical and analytical methods to determine the answer or to achieve the goal. This can be done by looking at the data visually or by doing regression analysis, testing the hypothesis and so on. The results of the analysis are then used to determine what actions are able to support the goals of the organization.
