Portuguese Language

Q&A for linguists, teachers and learners wanting to discuss the finer points of the Portuguese language


The best time here is when the delay between a question and an accepted
answer is shortest.

On the graph, look for the value on the x-axis that
corresponds to the minimum value on y-axis.
That's the best time to ask questions as defined above.

As for Dec 2013, the smallest time-to-answer was for questions asked
on Saturday at 1pm GMT. The asker had to wait for only 78 minutes.

- X: Hours, days of week, or both
    1.0 is Sunday, 12am GMT; 3.5 means Tuesday, 12pm GMT.
- Y: Time-to-answer. The average difference between the time when
    the question was created and when the accepted answer was created.

- All: Include all users of only one specified by UserId
    Values: 0 - show stats for one user, 1 - for all users
- Frequency: The scale of X-axis
    Values: 1 - hours, 2 - day of week, 3 - both
- MaxTimeDiff: The cut off value for time difference. All time-to-answer
    above this value will be excluded from the statistics.
    Default value: 1440 min (24 hours).
- UserId: Whose stats to include in calculations. Matters only when All = 0.
    Values: Your user ID or someone else's.

DECLARE @All int = ##All:int?1##
DECLARE @Frequency int = ##Frequency:int?3##
DECLARE @UsedId int = ##UserId:int##
DECLARE @YearsBack int = ##YearsBack:int?1##

;WITH tmp AS
  SELECT q.Title, q.AcceptedAnswerId,
         Period = CASE @Frequency
           WHEN 1 THEN DATEPART("hour", q.CreationDate)
           WHEN 2 THEN DATEPART("weekday", q.CreationDate)
           WHEN 3 THEN ROUND((CAST(DATEPART("weekday", q.CreationDate) AS numeric) +
             CAST(DATEPART("hour", q.CreationDate) AS numeric) / 24), 2) END

  SELECT Period, COUNT(case when AcceptedAnswerId > 0 then 1 else null end)/COUNT(*)
  --COUNT(*) AS [Total questions],
  --COUNT(case when AcceptedAnswerId > 0 then 1 else null end) AS [Answered questions]
