Critical Value in Statistics. In statistics, the critical value corresponds to a given significance level. This cutoff value determines the boundary between the two samples, on the basis of which it is determined, whether null hypothesis should be accepted or rejected.
Economic value is the maximum amount a consumer is willing to pay for an item in a free market economy or the amount of time an individual will sacrifice waiting to obtain a government-rationed good in a socialist economy. In contrast, market value represents the minimum amount a consumer will pay. Economic value thus often exceeds market value.
