Final answer:
To find the summation of the data set with observations 5, 1, 3, 2, and 1, add the numbers together to get a sum of 12.
Step-by-step explanation:
To find the sum of the given data set containing the observations 5, 1, 3, 2, and 1, you would add all the observations together:
- Add the first number: 5
- Add the second number: 1 (Sum is now 5 + 1 = 6)
- Add the third number: 3 (Sum is now 6 + 3 = 9)
- Add the fourth number: 2 (Sum is now 9 + 2 = 11)
- Add the fifth number: 1 (Sum is now 11 + 1 = 12)
So, the summation of the data set is 12.
