To find the mean (average) of a group of data items, follow these steps:

1. List the Data Items:
The given data items are 81, 78, 80, 73, 78, and 84.

2. Calculate the Sum of the Data Items:
Add all the data items together:
81 + 78 + 80 + 73 + 78 + 84 = 474

3. Count the Number of Data Items:
Determine how many data items are in the list. Here, the count is 6 since there are six numbers.

4. Divide the Sum by the Count:
To find the mean, divide the total sum of the data items by the number of data items.
Mean = Total Sum / Count
Mean = 474 / 6 = 79.0

Therefore, the mean of the given data items is 79.0.
