28,7,7,6,9,9,8,8

The numbers provided are: 28, 7, 7, 6, 9, 9, 8, 8. Here's a breakdown of key statistical measures and insights:

1. Measures of Central Tendency

( frac{28 + 7 + 7 + 6 + 9 + 9 + 8 + 8}{8} = frac{82}{8} = 10.25 )

Note: The outlier (28) heavily influences the mean.

Sorted data: 6, 7, 7, 8, 8, 9, 9, 28

Median = Average of 4th and 5th values = ( frac{8 + 8}{2} = 8 )

7, 8, 9 (each appears twice).

The data is multimodal.

2. Spread and Outliers

The outlier (28) creates a large spread.

28 is an outlier.

3. Data Without the Outlier

If we exclude 28:

Key Takeaway

The outlier (28) skews the mean and range significantly. For a more robust measure of central tendency, use the median (8). The modes (7, 8, 9) indicate multiple common values in the dataset.
