Hypothesis Testing
Hypothesis Testing
Hypothesis testing is a statistical method that is used to determine whether there is evidence to support a claim made about a population. It is a three-step process:
- Formulate a hypothesis: The hypothesis is a statement about a population parameter that you want to test. It can be either a null hypothesis (H0), which is the statement that there is no difference between the observed value of the parameter and the hypothesized value, or an alternative hypothesis (H1), which is the statement that there is a difference.
- Conduct a statistical test: The statistical test is a procedure that is used to calculate the probability of obtaining the observed results if the null hypothesis is true. This probability is called the p-value.
- Make a decision: If the p-value is less than a predetermined significance level (usually 0.05), then you reject the null hypothesis and accept the alternative hypothesis. Otherwise, you fail to reject the null hypothesis.
Hypothesis testing is used in a wide variety of fields, including science, engineering, business, and medicine. It is an essential tool for making informed decisions about populations.

Our Customers Say
I was at WooliesX (Woolworths) and we used Alooba and it was a highly positive experience. We had a large number of candidates. At WooliesX, previously we were quite dependent on the designed test from the team leads. That was quite a manual process. We realised it would take too much time from us. The time saving is great. Even spending 15 minutes per candidate with a manual test would be huge - hours per week, but with Alooba we just see the numbers immediately.
Shen Liu, Logickube (Principal at Logickube)
We get a high flow of applicants, which leads to potentially longer lead times, causing delays in the pipelines which can lead to missing out on good candidates. Alooba supports both speed and quality. The speed to return to candidates gives us a competitive advantage. Alooba provides a higher level of confidence in the people coming through the pipeline with less time spent interviewing unqualified candidates.
Scott Crowe, Canva (Lead Recruiter - Data)
How can you accurately assess somebody's technical skills, like the same way across the board, right? We had devised a Tableau-based assessment. So it wasn't like a past/fail. It was kind of like, hey, what do they send us? Did they understand the data or the values that they're showing accurate? Where we'd say, hey, here's the credentials to access the data set. And it just wasn't really a scalable way to assess technical - just administering it, all of it was manual, but the whole process sucked!
Cole Brickley, Avicado (Director Data Science & Business Intelligence)
The diversity of our pool has definitely improved so we just have many more candidates from just different backgrounds which I am a huge believer in. It makes the team much better, it makes our output much better and gives us more voices in terms of building the best product and service that we can.
Piers Stobbs, Cazoo (Chief Data Officer)
I wouldn't dream of hiring somebody in a technical role without doing that technical assessment because the number of times where I've had candidates either on paper on the CV, say, I'm a SQL expert or in an interview, saying, I'm brilliant at Excel, I'm brilliant at this. And you actually put them in front of a computer, say, do this task. And some people really struggle. So you have to have that technical assessment.
Mike Yates, The British Psychological Society (Head of Data & Analytics)
We were very quickly quite surprised with the quality of candidates we would get from Alooba. We ended up hiring eight different analysts via Alooba in about a year's time, which is quite extraordinary for us because we actually have almost never used a recruitment agency for any role. It has been our best outsourcing solution by far.
