This free A/B test calculator will help you compare two variants of your website, A and B, and tell you the probability that B is better. You can read more about A/B testing in our earlier blog post on the subject. You may also be interested in our Chi-Squared sample size calculator which will help you calculate the minimum sample size needed to run a Chi-Squared test, given an expected standardised effect size.

You most commonly hear about A/B testing in the context of commercial websites, but A/B testing can be done in a number of different contexts, including offline marketing, and testing prices.
You are probably familiar with traditional databases. For example, a teacher at a school will need to enter students’ grades into a system where they get stored, and at the end of the year the grades would need to be retrieved to create the report card for each student. Or an employee database might store employees’ home addresses, pay grades, start dates, and other crucial information. Traditionally, organisations use a structure called a relational database, where different types of data are stored in different tables, with links between them, and they can be queried using a special language called SQL.
A problem we’ve come across repeatedly is how AI can be used to estimate how much a project will cost, based on information known before the project begins, or soon after it starts. By “project” I mean a large project in any industry, including construction, pharmaceuticals, healthcare, IT, or transport, but this could equally apply to something like a kitchen renovation.
What is generative AI consulting? We have been taking on data science engagements for a number of years. Our main focus has always been textual data, so we have an arsenal of traditional natural language processing techniques to tackle any problem a client could throw at us.
Image above: the winning teams and participants in the Harmony AI hackathon on 3 June 2024 AI Hackathons: A Playground for Innovation What is an AI hackathon? A hackathon is an event that may last for a day or several days where people collaborate to solve a problem. The word “hackathon” is a portmanteau of “hack” and “marathon”. The first hackathon was held in 1999 by OpenBSD in Calgary, Canada[1]. Initially, hackathons were used for software development problems, but now organisations are running hackathons for a much more eclectic range of tasks, such as planning the marketing strategy of a nonprofit, and now there are AI hackathons.

AI in business and industry Artificial intelligence (AI) is a hot topic in business, but many companies are unsure how to leverage it effectively. I will discuss some practical applications of AI, focusing on areas where it can deliver real impact.
What is NLP in business environments? Natural language processing (NLP) is a branch of AI (Artificial Intelligence), empowering computers to not just understand but also process and generate language in the same way that humans do. A prime example is how Google’s algorithm works to provide relevant results when people enter specific search terms.
The impact of AI on human resources The world of work is rapidly changing, both due to traditional data science practices being adopted by more organisations, and due to the increasing popularity of generative AI tools such as ChatGPT, and Google’s BARD among non-technical workers. AI has the potential to boost global GDP by 7%, with the loss of millions of jobs, although it will also create new jobs for the displaced workers, according to a 2023 editorial by Goldman Sachs.
