You'd expect BI people to have a proper grounding in statistics but they haven't. It is very rare for someone who gives themselves a fancy title like this to be able to explain what a normal distribution or whether a finding is statistically significant.
You'll get a BI person to come up with an 'actionable insight' (whatever the hell they think that is).
' Oh? Is that statistically significant?' I ask.
'Yeah' they say.
'Interesting, can I see the calculations, please?'
'Yes, what is the probability level' (blank look from BI person
) 'So what do you mean by 'significant'"
'Well, management will really go for it. It will get them really interested'
