Final answer:
The mean for the given data set is 52.
Step-by-step explanation:
To find the mean, you need to sum up all the data items and divide by the total number of items. For the given data set: 54, 51, 53, 46, 51, 57, the sum of all the items is 312. Since there are 6 items, you divide the sum by 6 to get the mean. So, the mean is 312/6 = 52.
