The following data was collected from 10 visitors to Disneyland. A researcher stood at the entrance gate and interviewed the first 10 families that agreed to participate. Each family was asked, “How many times have you been to Disneyland?” The data values were: 1, 1, 2, 2, 2, 2, 3, 3, 4, 7. The average number of visits was calculated and reported.

Find the range of data values

The range of the given data set is 6.

Step-by-step explanation:

Range of the data set provides us with some basic information regarding spread of the data.

It is commonly used and quite easy to find.

First step is to arrange the values from the lowest to the highest.

It is already given arranged, so that will savd us some time.

Next step is simply subtracting the two values on the extremes, or, simply put, subtract the lowest from the highest value.

So, the range in this case would be 7-1=6.
