You use a t-scoreâalso known as a Student's t-distributionâwhen you want to estimate a population statistic, such as the mean, or compare two groups of data. The t-score gives good results from small samples as long as the sample data form a bell-shaped curve when graphed.
The only fortified wine that can stand open any length of time is Madeira. That'll be good for 6 months. All the rest (port or sherry or marsala), depending on what it is exactly, only maximum, 2 weeks. After that, absolutely no good. And even 2 weeks is pushing it for some fortified wines. cheers, Bonnie.
How Long Does A Wine Keep? The people who head to the store on the way home to pick up a bottle of wine for dinner have it right. Most wine â and by âmostâ I mean 95% of it â is meant to be enjoyed, if not shortly after purchase, then within 12 to 18 months of the vintage date.
