Designing an experiment involves using a control, a large and random sample, specifying a timeframe, calculating a mean, using appropriate statistical tests, and stating a null hypothesis.
La progettazione di un esperimento prevede l'uso di un controllo, un campione ampio e casuale, la specificazione di un intervallo di tempo, il calcolo di una media, l'uso di test statistici appropriati e l'enunciazione di un'ipotesi nulla.
| Front | How do you design an experiment? |
|---|---|
| Back | - control? - large sample so that it's representative- random sample so it's unbiased - specify time frame - calculate mean - why this stat test - null hypothesis - if x>|c|, difference/correlation is significant - less than 5% probability that results are due to chance - we reject the null hypothesis |
