Our Goals today? • To discover more about iNZight • To share knowledge about statistics and iNZight • To know where to find resources • To have a bit of fun learning • And…know that data needs to be owned, personalised or it is just nonsense. Go get your own!
Randomisation • So how do you know if a perceived difference is due to random variation or not? • How can we use iNZight to help answer this?
Bootstrapped • What? • How? • Teaching and Learning?
Experiment • Is the milk in the new triple layer “see thru cow” container any better than the milk in the old see through one layer container? • How can I know? • Can iNZight help here?
What! • Rugs • Jitter • Residuals • Time
Start Exploring • Get some data you know something about…context! • Ask questions about the data • This is Statistics….PPDAC • Statistics usually starts with a question • “I wonder what relationship there is between student absence and credits gained?”
