Question

What is the sum of squared scores (2x2) for this set of data? 14, 11, 7, 16

Answer 1

The sum of squared scores for the given set of data (14, 11, 7, 16) is calculated by squaring each number and then adding them together, resulting in a total of 622.

Step-by-step explanation:

Calculation of Sum of Squared Scores (2x2)

To find the sum of squared scores for the given set of data (14, 11, 7, 16), we must square each data point and then add them together. Here is the step-by-step calculation:

1. Square each number: $14^2 = 196$, $11^2 = 121$, $7^2 = 49$, $16^2 = 256$.
2. Add the squared numbers together to get the sum: $196 + 121 + 49 + 256$.
3. The sum of squared scores (2x2) is $196 + 121 + 49 + 256 = 622$.

This value, 622, is used in various statistical calculations such as computing variance or the sum of squares error in an ANOVA table.
