What Is the Difference Between Descriptive Analysis and Inferential Analysis?

Descriptive analysis is exactly what it sounds like. It describes the data. This is very useful because it allows you to quickly see the fundamental characteristics of your data and the information you are working with. The most common descriptive statistics are the range (the difference in highest and lowest scores), minimum and maximum (the lowest or highest scores in a data set), and frequency (how frequently a particular value appears in the data set).

Methods for Quantitative Data Analysis

There are many techniques that can be used to derive insights from quantitative data. These are some of the most popular and useful methods for quantitative data analysis:

Regression analysis: This method is used to determine the relationship between variables and see if they have any correlation. Regression can be used to forecast future trends and make predictions.

Monte Carlo simulation: The Monte Carlo algorithm is a computer-based technique that generates models of possible outcomes and probability distributions from your data. It considers all possible outcomes and calculates the likelihood that each one will happen. Data analysts use it to perform advanced risk analysis to predict the future.

Cohort analysis: A cohort can be defined as a group of people that share an attribute or behavior over a time period. For example, a cohort made up of students who started university in 2020 or customers who bought via your app during February. Cohort analysis basically divides your data into cohorts, and analyses how they behave over time. This is particularly useful in identifying patterns and adapting your products or services to them.

Cluster analysis: This exploratory technique is used to find patterns in a dataset. Cluster analysis seeks to group different data points into groups that can be both internally homogenous or externally heterogeneous. In other words, data points in a cluster may be similar but not identical to other data points. Clustering can be used to determine how data is distributed within a dataset or as a preprocessing step in other algorithms.

This analysis is used to identify patterns and cycles over time. A time series is a collection of data points that measure the same variable at different times. For example, weekly sales figures or monthly sign-ups for email. Analysts can predict how the variable of their interest will fluctuate in the future by looking at trends over time. This is extremely useful when making business decisions.
