Insensitivity to sample size is a cognitive bias that occurs when people judge the probability of obtaining a sample statistic without respect to the sample size. For example, in one study subjects assigned the same probability to the likelihood of obtaining a mean height of above six feet [183 cm] in samples of 10, 100, and 1,000 men., To demonstrate how the porosity predictions using the Оµ-insensitivity loss function are correlated to the actual core-measured data, the mean of the correlation coefficient of predictions obtained from the SVM regression using RBF and sigmoid kernel functions, and MLP models over all sample sizes obtained from 50 random realizations are plotted as shown in Fig. 12..

Another major effect on probability is sample size. The similarity of sample statistic to a population parameter does not depend on size; therefore, if probabilities are assessed by representativeness, the probability is independent of sample size.

A failure to take account of sample size when estimating the probability of obtaining a particular value in a sample drawn from a known population. Research into the fallacy was first reported by the Israeli psychologists Daniel Kahneman (born 1934) and Amos Tversky (1937вЂ“96) in an article in the journal Cognitive Psychology in 1972
