AnalyticsRe: World Statistics Day Question 1: In your own work with data, what steps do you take to ensure that your data is trustworthy?OK, I'll play. One of the first things I think about is measurement error. I don't trust any measurement system unless it's been studied. Typically, I'll start with sampling to understand the stability and size of the measurement errors (precision: repeatability & reproducibility) and compare those sources to the other sources I wish to discriminate.
Re: World Statistics Day Question 1: In your own work with data, what steps do you take to ensure that your data is trustworthy?Ask questions!
Hearing someone explain where data came from or how it was collected sometimes exposes some of the limitations of that data, including culturial bias discussed by Shankar Vedantam in his Fireside Chat from the Discovery Summit Americas last week.
Re: World Statistics Day Question 1: In your own work with data, what steps do you take to ensure that your data is trustworthy?It took awhile...but during my tenure in industry...I was always trusting of the plan we articulated for the execution of a designed experiment was, in fact, what happened during execution, and to vehemently agree with @statman 's earlier reply, measurement of responses. Things like, randomization, blocking, did they really set the factors at the prescribed levels, any noticeable noise variables we didn't anticipate??? and on and on. Only after discovering that all too frequently our plan was NOT executed that I decided that to help with 'trustworthiness', I had to be present for experimental design execution and measurement work. Meant alot of long nights on 'C' shift, or learning new processes to ask the critical questions...but we ALL felt that our data was more trustworthy.
In the Toyota Production System there is a concept called 'Gemba'...which loosely translated means 'go to where the work is done and see.' That's what I tried to do.
Re: World Statistics Day Question 1: In your own work with data, what steps do you take to ensure that your data is trustworthy?In my case measurement system and replication/verification. The physical manifestations of the handling in a chemical process does not lie.
Re: World Statistics Day Question 1: In your own work with data, what steps do you take to ensure that your data is trustworthy?Lots of great answers already. I will add, plot the data. I like distributions, fit y by x (if I have groups to compare), and the multivariate scatter plots for starters.
