Final answer:
The mean is 3.5, the median is 3, the mode is 7, and the range is 6.
Step-by-step explanation:
The mean of the given list of values 1, 2, 4, 7 is 3.5, as you add up all the values and divide by the total number of values (4).
The median is 3, which is the value in the middle when the list is arranged in ascending order.
The mode is 7, which is the value that appears most frequently in the list.
The range is 6, which is calculated by subtracting the smallest value (1) from the largest value (7).
