| surob | Can someone explain what it means? Didn't quite understand. Thx |
| bobert | I think it means that the because it is an estimate, it is acknowledging that there is uncertainty or chance in the estimation. Analogy: A person robs a store that you are at. The police come to you for a statement and ask how confident you feel about picking the man out of a lineup. You say 95%. You are not saying that you are 100% sure because there is a chance that you won't be able to. |
| epizi | I think chance is about probability of the right guess.If you are given a reasonable range to choose, chance of missing(getting) the right guess is reduced(increased) |
| Shalva | You cannot eliminate uncertainty simply by calculating the confidence interval. |
