DATA PREP
1. Add a column to the right of “Worldwide Gross”, called Gross Sales equal to the sum of “Worldwide Gross” and “US Gross”.
2. Add a column to the right of Gross Sales called Avg Gross Box Office Sales. Apply the following calculation:
=IF(AND(B2>0, C2>0),AVERAGE(B2:C2), IF(AND(B2=0, C2>0),C2, 0))
3. For “Release Date”, add columns Release Month and Release Year. Use appropriate functions. Review Common Data Prep Functions as needed.
4. Add a column called Release Decade. Apply the following function: Note: J is the column for “Release Year” created above. Your column may be different. I suggest you copy and paste into a text editor and update as needed. Do not use MS Word, it needs to be text only. You can use this online text editor: https://www.onlinetexteditor.com/
=IF(VALUE(J2)<1920,"1910s", IF(VALUE(J2)<1930,"1920s", IF(VALUE(J2)<1940,"1930s", IF(VALUE(J2)<1950,"1940s", IF(VALUE(J2)<1960,"1950s", IF(VALUE(J2)<1970,"1960s", IF(VALUE(J2)<1980,"1970s", IF(VALUE(J2)<1990,"1980s", IF(VALUE(J2)<2000,"1990s", "2010s")))))))))
5. Add a column called Rating Category to the right of “MPAA Rating” Apply the following function: Note: L is the column for “MPAA Rating”. Your column may be different
=IF(ISBLANK(L2), "N/A", VLOOKUP(L2,Ratings!$A:$B,2,0))
6. Add a column called Genre to the right of “Major Genre” Apply the following function: Note: Q is the column for “Major Genre”, Your column may be different
=IF(ISBLANK(Q2),"Other",IF(Q2="Black Comedy", "Comedy", Q2))
