Three scoring options for combining item responses in the final model were evaluated: 1) total sum of item responses, 2) dichotomous variable for each item, and 3) weighted sum of item responses.
Each bucket holds the total sum of the items that are stored in that bucket and the arrival time of the oldest element stored in that bucket.
The instrument measures generalised anxiety according to severity scales by scoring the simple total sum of the items, the total score ranging from 0 to 50.
In concrete terms, which situations fit the given data are identifiable by comparing the sum of the squared deviations (total sum of squares (TSS)), calculated from all items to one from the separated item sets (self-focused and task-focused) for each situation, which is represented as a ratio between TSS of all items and one of the separated item sets.
For these analyses, we used the total sum of all six K-SADS sleep item scores at baseline (1 3 points per item, minimum 6 points, maximum 18 points; missing answers were substituted with the average points of all items) to form a continuous measure of sleep complaints (sleep complaint severity score).
The psychometric results support the use of the SDS subscales (items 1-3) and total score (sum of items 1-3) in an ADHD population.
When presented with two trays, each tray containing two separate sets of food items, chimpanzees and capuchin monkeys select the greater total, indicating that they consider the sum of items [25] [27].
The HSCL total score is the sum of items divided by the number of items answered.
The scores from each category were added to form three scores: inattentive score (sum of items 1 to 9), hyperactive/impulsive score (sum of items 10 to 18) and total score (sum of items 1 to 18).
Total scores were obtained by adding the sum of items and dividing them by the number of items answered.
Inter-item correlations were calculated to reveal any redundancy in measured items and corrected item-total correlations (sum of the all item scores without including the item in question) were calculated to reveal any item that could possibly belong to a different construct than the one targeted.
