    • Data Analtyics Bootcamp - June 2025 Class ([Week 1] Introduction to Excel Analytics - 2-1. Overview of Basic Excel Formulas(SUM, AVERAGE, COUNTA))

      1. Timestamp: 2:25
      2. Question about the lecture:

       

      According to the video, COUNTA(UNIQUE(start:end)) is being used but mine doesn't allow me to use "UNIQUE" command with red underlinee marked (error).

      Currenlty using Microsoft Excel without any subscriptions or promotion that requires monthly payment. In order to use UNIQUE, should I pay for EXCEL?? 

      Thank you.
