Typing Test: Speed Versus Accuracy in Board Registration Data
You are a Junior Assistant in a CBSE regional office. The board's Class X registration portal closes at 5:15 p.m. today; 1,260 candidate records must be keyed in by then. You type at 42 wpm with about 96% accuracy in practice. At 2 p.m. you have completed 860 records. A spot check of 50 records finds 4 errors: two wrong subject codes, one transposed date of birth, one misspelled guardian name. The portal rejects any record where subject code and fee category mismatch. At your current pace, the remaining 400 records need about 75 minutes, leaving 45 minutes before the lock. Your supervisor says "finish and submit; corrections can be done later," but the portal does not allow edits after lock, and corrections need a formal request next week, which may delay admit cards. A second operator is free for 30 minutes but does not know the subject-code list. Need decide.
1. What is the most defensible course of action for the next 30 minutes, and why?

Do not simply finish and submit. The sample rate is 4/50 = 8%, so the 860 completed records could contain roughly 69 errors if the sample is representative; even a much lower true rate would produce several portal-blocking rejects. The defensible action is a triage, not a full stop: (1) correct the four detected records immediately; (2) give the second operator a printed subject-code/fee-category matrix and assign her only to verify those two fields on the 860 completed records; (3) you continue keying the remaining 400, because stopping all entry creates a guaranteed shortfall; (4) at 4:45 p.m. run the portal validation batch and fix every rejection; (5) ask the supervisor now, in writing, to request a short portal extension. The key reasoning is that identity and fee-code errors are irreversible after lock, while spelling errors are lower risk and can follow the correction route.
2. How should the 50-record sample be used to estimate overall error exposure, and what threshold would trigger a full re-check?

Treat 4/50 as a provisional rate, not a precise estimate: with only 50 records the uncertainty is wide, so do not rely on the 96% practice figure. Stratify by error type. Subject-code and fee-category errors are portal-blocking, so they justify a 100% check of those fields across all 860 records. Date-of-birth errors are identity risks and also justify a full check. Guardian-name spelling can be sampled: check another 50 records after correction, and if two or more name errors appear, extend to all records. Set the trigger in advance: any portal rejection, any mismatch between subject code and fee category, or any error affecting candidate identity means full re-check of that field, not merely the record where it was found. This prevents the common mistake of correcting only the visible sample and assuming the rest are clean.
3. Draft a short escalation note to the supervisor (3-4 sentences) that states the risk without being insubordinate.

Sir/Madam, at 2 p.m. a 50-record check found 4 errors (8%), including two subject-code errors and one date-of-birth error. At the current pace the remaining 400 records will be entered by about 3:15 p.m., but only 45 minutes will remain for validation before the 5:15 lock. I propose to deploy the second operator on subject-code and fee-category verification while I continue entry, and I request that you seek a written portal extension to 6 p.m. Submitting without this check risks portal rejections and admit-card delays; please confirm the approach.
