This document provides an overview of quantitative techniques taught in a B.Com program. It discusses types of classification, including classification by time, space, and attributes. It also discusses types of frequency distributions, including individual, discrete, and continuous distributions. Specifically, it defines continuous distributions as those where variables can take any value between minimum and maximum, and defines key terms for continuous distributions like class limits, class intervals, class frequency, and cumulative frequency. The document aims to help students understand how to present and analyze data through classification and frequency distributions.
