1. Set up your next blank notebook page as shown below CW #9 : MAKING DATA TABLES AND GRAPHS Part A: Teacher Example Problem: Data and Results: (leave at least 8 lines to write your Data table) Graph Step 1: figure Out the problem or question Is the sea otter population increasing, decreasing Or remaining steady ?

2. CW #9 : MAKING DATA TABLES AND GRAPHS Part A: Sea Otters Problem: Is the sea otter population increasing, decreasing or remaining steady ? Step 1: figure Out the problem or question

3. CW #9 : MAKING DATA TABLES AND GRAPHS Part A: Sea Otters Problem: Is the sea otter population increasing, decreasing or remaining steady ? Step 1: figure Out the problem or question Step 2: Record your observations Data And Results In year one of the study (1962) they counted 46 otters. Eight years later the count was 42. In 1982 the count was 35. Ten years later it dropped to 30. At last count in 2002, the count of was 26.
