Mhinduro uye tsananguro zvinoonekwa paunenge uchitora bvunzo.

  1. Sei zvikwata zveA/B zvichiedza modhi mukugadzira pane kuvimba nemametrics ekunze?
    • Iyo modhi ine zvirinani kunze kwenyika inogona kuramba ichikuvadza chaiyo bhizinesi metrics
    • Mametrics ekunze haabvumirwe nemutemo
    • Kugadzira kwakachipa pane kuyedza pasina Indaneti
    • Hapana data yeOffline
  2. Ibasa rei rinoitwa zvisina tsarukano muyedzo yeA/B?
    • Inoita kuti bvunzo imhanye nekukurumidza
    • It supports balance between groups in expectation, subject to design and implementation assumptions
    • Inobvisa vashandisi vakarerekera
    • Inoderedza nhamba yemhando dzinodiwa
  3. In a model A/B test, what usually happens in the treatment group?
    • The candidate scores requests but all outputs are withheld
    • Every user is assigned to both models for the same decision
    • The candidate model serves user-facing decisions for the randomly assigned group
    • The control model is removed before any comparison
  4. Under a null hypothesis and stated test assumptions, how is a p-value interpreted?
    • As the probability that the null hypothesis is true
    • As the probability that the treatment caused the observed result
    • As the probability that the experiment will replicate
    • As the probability of data at least this extreme if the null hypothesis holds
  5. How can a multi-armed bandit change an experiment while it runs?
    • It can allocate more traffic to variants with better observed outcomes and less to others
    • It keeps every variant at a fixed equal allocation throughout
    • It removes randomization from every assignment
    • It guarantees the best variant is identified without uncertainty
  6. Chii chinangwa chekuongorora simba pamberi pebvunzo yeA/B?
    • Kusarudza logo yekuedza
    • Kufungidzira kuti vangani vashandisi vanodiwa kuti vaone nekuvimbika maitiro chaiwo
    • Kuti encrypt traffic
    • Kudzima boka rekutonga
  7. What does a sample-ratio mismatch (SRM) signal during an A/B test?
    • The treatment model is necessarily better
    • The experiment has sufficient statistical power
    • Observed assignment counts differ materially from the configured allocation, which can indicate a data or randomization problem
    • The primary metric improved causally
  8. Why include guardrail metrics alongside an experiment’s primary success metric?
    • To guarantee the candidate wins on every metric
    • To replace the primary metric after results are observed
    • To avoid defining a decision rule before the test
    • To detect meaningful harms in other outcomes even when the primary metric improves
