Line of Best Fit: Last Topic, then done the review packet
Ex 1: The chart below gives the number of visitors to an art exhibit during the first 6 days of August
The Line of Best Fit is used to make assumptions and predictions about data
DayNumber of
Visitors
1 200
2 175
3 190
4 189
5 170
6 172
Calculate the line of best fit using the calc
Step 6 on handout
