Explanation written with AI and checked against the answer key

Analyze the question: The "modal value" is the mode, which is the value that appears most often in a data set. Concept: To find the mode, count how many times each number occurs. The number with the highest frequency is the mode. Solution: Data: 3, 8, 4, 6, 3, 5, 2, 7, 3, 5 | Value | Frequency | |-------|-----------| | 2 | 1 | | 3 | 3 | | 4 | 1 | | 5 | 2 | | 6 | 1 | | 7 | 1 | | 8 | 1 | The number 3 appears three times, more than any other value (5 appears twice). So the mode = 3. Tip: Mode = "most" (both start with "Mo"). Make a quick tally table so you don't miss repeated numbers. Remember too that a data set can have more than one mode (bimodal) or none, so always check that no other value ties for the highest frequency.
