8.4, 9.4, 14.2, 5.6, 8.3, 9.0, added together
To find the mean absolute deviation (MAD), follow these steps:
1. Find the mean of the dataset.
Mean = (8.4 + 9.4 + 14.2 + 5.6 + 8.3 + 9.0 + 10.2) / 7
Mean = 65.1 / 7
Mean ≈ 9.3
2. Subtract the mean from each data point and take the absolute value.
|8.4 - 9.3| = 0.9
|9.4 - 9.3| = 0.1
|14.2 - 9.3| = 4.9
|5.6 - 9.3| = 3.7
|8.3 - 9.3| = 1.0
|9.0 - 9.3| = 0.3
|10.2 - 9.3| = 0.9
3. Find the mean of the absolute values calculated in step 2.
MAD = (0.9 + 0.1 + 4.9 + 3.7 + 1.0 + 0.3 + 0.9) / 7
MAD ≈ 1.7
Therefore, the mean absolute deviation of the given dataset is approximately 1.7.
To add these numbers together, you simply need to sum them up:
8.4 + 9.4 + 14.2 + 5.6 + 8.3 + 9.0
When you add these numbers together, you get a sum of 54.9.
8.4, 9.4, 14.2, 5.6, 8.3, 9.0, 10.2. added together
To find the sum of these numbers, you need to add them all together:
8.4 + 9.4 + 14.2 + 5.6 + 8.3 + 9.0 + 10.2 = 65.1
So, when you add these numbers together, the sum is 65.1.
