Hypothesis Testing – Part 19 | Chi-Squared Test - CFA Level 1 (QM)

In this lecture, we discuss the Chi-Squared Test, an important non-parametric statistical test used when we are working with categorical data and frequencies. The focus is on understanding the intuition behind the Chi-Squared Test, how the test statistic is calculated, and how the final statistical conclusion is drawn. Topics Covered: • Meaning and purpose of the Chi-Squared Test • Understanding observed and expected frequencies • Formulation of Null and Alternative Hypotheses • Calculation of the Chi-Squared test statistic • Degrees of freedom • Decision rule and critical value approach • Interpretation of the test result • Drawing the appropriate statistical conclusion • Practical approach to solving examination-oriented questions This lecture is part of the Hypothesis Testing Series, where statistical concepts are explained in a simple, logical, and application-oriented manner. The objective is to understand when a Chi-Squared Test should be used, how the test statistic is constructed, and how to interpret the result correctly, rather than simply memorising the formula.
