Answer
To evaluate the reliability of the tests, we will start by calculating the range of scores for each test. The range is determined as follows:
Test 1: Range = Highest score - Lowest score = 10 - 0 = 10
Test 2: Range = 8 - 2 = 6
Test 3: Range = 10 - 4 = 6
Test 4: Range = 6 - 4 = 2
Step 2

Answer
From the calculated ranges, we observe:
Test 1: Range = 10
Test 2: Range = 6
Test 3: Range = 6
Test 4: Range = 2
The smallest range indicates the least variability in scores, suggesting higher reliability.
