Average Weekly Screen-Time Hours Calculator
Actual independently aggregated weekly screen-time minutes to observed mean hours. Complete compatible observation periods required; no inferred health or attention outcomes.
Description
Weekly screen-time records can be converted from minutes to mean hours per observed week.
Weekly screen-time records can be converted from minutes to mean hours per observed week.1
Device coverage, overlap and the definition of screen use need to be established independently.
When to use Average Weekly Screen-Time Hours Calculator
Use this tool to obtain observedMeanHours from the supplied records using the stated calculation. Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
How to use Average Weekly Screen-Time Hours Calculator and understand its results
- Establish the population, period, variable definitions, sample coverage and independently applicable instrument or calibration.
- Enter observedWeeklyScreenMinutes, using the field meanings and rules below, then run the tool.
- Read result.observedMeanHours. Use the units and sign conventions below, and review any unknown records separately.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| observedWeeklyScreenMinutes | Observed weekly screen minutes | list of number | Required |
Require a nonempty nonnegative list of minutes for independently defined weekly observation periods. Compute their arithmetic mean and divide by sixty for mean hours per recorded period. No calendar filling, overlapping-device adjustment or measurement verification is added.
meanHours=mean(recordedMinutes)/60 Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Calculated observation or qualified reference | object |
| result.observedMeanHours | Arithmetic mean of recorded minutes divided by sixty, per the declared daily or weekly period. | number |

}Limitations and assumptions
Population definitions, survey design, calibration and observation coverage are independently established. A result describes the supplied record or conditional model without demonstrating causation, validating an instrument or supplying representative population evidence.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries, subject to the narrower lengths and code rules above. Extremely large composite outputs are rejected.
