Q. Aaron has the following data:11,1,r,6,5If the mode is 5, which number could r be?Choices:(A)6(B)5
Understand the problem: Step 1: Understand the problem and identify what is asked.We need to find the value of r such that the mode of the dataset 11,1,r,6,5 remains 5. The mode is the number that appears most frequently in a dataset.
Analyze choices: Step 2: Analyze the given choices for r. Choices are: (A) 6 (B) 5 Since the mode is the number that appears most frequently, r must be a number that does not change the mode of the dataset.
Check r=6: Step 3: Check if r=6 affects the mode.If r=6, the dataset becomes 11,1,6,6,5. Here, both 6 and 5 appear twice. This would mean there are two modes, which is not allowed as per the problem statement that specifies the mode must be 5.
Check r=5: Step 4: Check if r=5 affects the mode.If r=5, the dataset becomes 11,1,5,6,5. Here, 5 appears three times, making it the clear mode of the dataset.
