data set of numbers with mode 7, median 12, range 13, and maxium 18

range 13?

5, 7,7,7,12,13,15,16,18

To find a dataset of numbers with a mode of 7, median of 12, range of 13, and a maximum of 18, we can use a combination of different numbers that satisfy these conditions.

First, let's address what each of these terms mean:

- Mode: The mode is the value that appears most frequently in a dataset. In this case, the mode is 7, indicating that 7 should appear more times than any other number in the dataset.

- Median: The median is the middle value in a dataset when the numbers are arranged in ascending or descending order. In this case, the median is 12, implying that the numbers in the dataset should be placed in order, and the 12th number in this ordered list will be the median.

- Range: The range is the difference between the maximum and minimum values in a dataset. In this case, the range is 13, indicating that the difference between the maximum and minimum numbers in the dataset should be 13.

- Maximum: The maximum is the highest value in a dataset. In this case, the maximum is 18, so no number in the dataset should exceed 18.

Based on these criteria, we can create a possible dataset like this:

3, 3, 7, 7, 7, 10, 12, 12, 12, 12, 15, 18, 18

In this dataset, the mode is 7, as it appears more frequently than any other number. The median is 12, as it is the middle value when the numbers are arranged in ascending order. The range is 15 (18 - 3 = 15), as the difference between the maximum (18) and minimum (3) values is 15. And finally, the maximum value is 18, as no number in the dataset exceeds 18.

However, it's important to note that this is just one example of a dataset that satisfies the given conditions. There might be several other datasets that meet these criteria as well.
