There is an error in the first sentence of the "Imperfect streaks consisting of hot (cold) streaks with up to one miss (hit)" portion of the “Method” subsection of the "Phase 2: How Do the Analyzed Metrics Change in Relation to Streakiness?" section. The correct sentence is: As hypothesized above, hot (cold) streaks might end with difficult (easy) shot attempts, and a key question about the traditional definition of the hot hand is whether a miss off a difficult FGA is sufficient for a hot streak to be considered as ended in a player’s and an observer’s mind. Table 1 has been corrected for improved readability. Please see the corrected Table 1 here.
