9 reasons why

Adaface Statistics Assessment Test is the most accurate way to shortlist Statistikers

Reason #1

Tests for on-the-job skills

The Statistics Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

Forståelse af grundlæggende begreber og principper for statistik
Anvendelse af statistiske teknikker til at analysere data og drage konklusioner
Fortolkning af p-værdier og konfidensintervaller for at foretage konklusioner
Prøveudtagningsdata og forståelse af prøveudtagningsfordelinger
Brug af regressionsanalyse til at analysere forholdet mellem variabler
Gennemførelse af efterforskningsdataanalyse for at forstå mønstre og tendenser
Anvendelse af ikke-parametriske statistikker til dataanalyse
Forståelse af sandsynlighedsteori og dens anvendelser
Analyse af data ved hjælp af forskellige dataanalyseteknikker

Reason #2

No trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Statistik test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Forståelse af grundlæggende statistikker
Evne til at anvende inferenssteknikker såsom p-værdier og konfidensintervaller
Kendskab til metoder til prøveudtagning af data
Færdighed i regressionsanalyse
Forståelse af prøveudtagningsfordelinger
Evne til at udføre efterforskende dataanalyse
Kendskab til ikke-parametrisk statistik
Dygtighed i sandsynlighedsberegninger
Færdighed i dataanalyse
Erfaring med statistiske softwarepakker

Once the test is sent to a candidate, the candidate receives a link in email to take the test. For each candidate, you will receive a detailed report with skills breakdown and benchmarks to shortlist the top candidates from your pool.

What topics are covered in the Statistics Test?

inferens: p-værdier og konfidensintervaller
inferens: p-værdier og Tillidintervaller fokuserer på statistisk inferens, som involverer at gøre konklusioner eller forudsigelser om en population baseret på eksempeldata. Denne færdighed måles i testen for at evaluere en kandidats evne til at udføre hypotesetest og bestemme betydningen eller konfidensniveauet for statistiske resultater.
dataprøveudtagning
Data -prøveudtagning refererer til processen med Valg af en undergruppe af observationer fra en større population til statistisk analyse. Denne færdighed måles i testen for at måle en kandidats viden om forskellige prøveudtagningsteknikker, forståelse af prøveudtagningsfordeling og evnen til effektivt at indsamle repræsentative data.
regression
Regressionsanalyse er en statistisk teknik, der bruges til at modellere og analysere forholdet mellem variabler. Denne færdighed måles i testen for at vurdere en kandidats færdigheder i montering af regressionsmodeller, fortolkning af koefficienter og foretagelse af statistik beregnet ud fra forskellige prøver af den samme population. Denne færdighed måles i testen for at evaluere en kandidats forståelse af prøveudtagningsfordelinger, herunder den centrale grænse sætning og begrebet standardfejl.
efterforskende dataanalyse
Exploratory Data Analysis (EDA ) involverer processen med at opsummere, visualisere og fortolke data for at få indsigt og identificere mønstre eller tendenser. Denne færdighed måles i testen for at vurdere en kandidats evne til at udføre dataudforskningsteknikker, såsom planlægning af grafer, beregning af sammenfattende statistikker og detektering af outliers eller manglende værdier.
ikke-parametriske statistikker </h4> < P> ikke-parametriske statistikker er statistiske metoder, der ikke antager nogen antagelser om den underliggende befolkningsfordeling. Denne færdighed måles i testen for at evaluere en kandidats viden og anvendelse af ikke-parametriske tests, såsom Mann-Whitney U-test eller Wilcoxon signeret-rank-test, når man beskæftiger sig med data, der ikke opfylder normalitetsantagelser. </p> < H4> Sandsynlighed
Sandsynlighed henviser til målet for sandsynligheden for en begivenhed, der forekommer, baseret på forholdet mellem gunstige resultater og de samlede mulige resultater. Denne færdighed måles i testen for at vurdere en kandidats forståelse af sandsynlighedsteori, herunder betinget sandsynlighed, uafhængige begivenheder og sandsynlighedsfordelinger.
dataanalyse
Dataanalyse omfatter processen med inspektion , rengøring, transformation og modellering af data for at opdage nyttige indsigt og støtte beslutningstagning. Denne færdighed måles i testen for at evaluere en kandidats færdigheder i at anvende statistiske teknikker og fortolke resultater for praktisk datadrevet problemløsning.

Statistics Hiring Test Ofte stillede spørgsmål

Kan jeg kombinere flere færdigheder i en brugerdefineret vurdering?

Ja absolut. Brugerdefinerede vurderinger er oprettet baseret på din jobbeskrivelse og vil omfatte spørgsmål om alle must-have-færdigheder, du angiver.

Har du nogen anti-cheating eller proctoring-funktioner på plads?

Vi har følgende anti-cheating-funktioner på plads:

Ikke-gåbare spørgsmål
IP Proctoring
Webproctoring
Webcam Proctoring
Detektion af plagiering
Sikker browser

Læs mere om Proctoring Features.

Hvordan fortolker jeg testresultater?

Den primære ting at huske på er, at en vurdering er et elimineringsværktøj, ikke et udvælgelsesværktøj. En færdighedsvurdering er optimeret for at hjælpe dig med at eliminere kandidater, der ikke er teknisk kvalificerede til rollen, den er ikke optimeret til at hjælpe dig med at finde den bedste kandidat til rollen. Så den ideelle måde at bruge en vurdering på er at beslutte en tærskelværdi (typisk 55%, vi hjælper dig med benchmark) og inviterer alle kandidater, der scorer over tærsklen for de næste interviewrunder.

Hvilken oplevelsesniveau kan jeg bruge denne test til?

Hver Adaface -vurdering tilpasses til din jobbeskrivelse/ ideel kandidatperson (vores emneeksperter vælger de rigtige spørgsmål til din vurdering fra vores bibliotek på 10000+ spørgsmål). Denne vurdering kan tilpasses til ethvert erfaringsniveau.

Får hver kandidat de samme spørgsmål?

Ja, det gør det meget lettere for dig at sammenligne kandidater. Valgmuligheder for MCQ -spørgsmål og rækkefølgen af spørgsmål randomiseres. Vi har anti-cheating/proctoring funktioner på plads. I vores virksomhedsplan har vi også muligheden for at oprette flere versioner af den samme vurdering med spørgsmål om lignende vanskelighedsniveauer.
