Insights

Discover trends in your data using modern SQL analytics.

Tip / fare correlation

A scatterplot correlating tips to total fare of a NYC taxi trip. Points in purple indicate those correlating to fixed percentages of the total fare -- 10%, 15%, 20%, etc., with a 1% tolerance.

 SELECT
  tip_amount,
  fare_amount,
  (
    abs(tip_amount / fare_amount - 0.1) < 0.01
    OR abs(tip_amount / fare_amount -0.15) < 0.01
    OR abs(tip_amount / fare_amount - 0.2) < 0.01
    OR abs(tip_amount / fare_amount - 0.3) < 0.01
  ) percent_tip
FROM
  trips
WHERE
  pickup_datetime BETWEEN 
    dateadd('m', -30, dateadd('y', 2015 - year(now()), now()))

      ORDER BY
        pickup_datetime RANGE BETWEEN 10 MINUTE PRECEDING
        AND CURRENT ROW
    ) avgFareHourlyMavg
  FROM trips
  WHERE
    pickup_datetime BETWEEN 
        dateadd('y', 2015 - year(now()), timestamp_floor('d', now()))
