1) What does the F crit mean?
2) What numbers represent the SST, SSE and SS Total?
3) What does the P-value number mean?
4) How do the F and F crit relate to each other? What do these numbers mean?
5) Re-run an ANOVA in Excel and determine if the average processing times between workers (employees are in rows) are the same or different.
