Three randomly selected households are surveyed. The numbers of people in the households are 1,1​ 3,3​ and 8,8. Assume that samples of size n =2 are randomly selected with replacement from the population of 1,1​ 3,3​ and 8,8. Listed below are the nine different samples. Complete parts​ (a) through​ (c).   1,1 1,3 1,8 , 3,1 3,3 3,8 , 8,1 8,3 8,8    a. Find the variance of each of the nine​ samples, then summarize the sampling distribution of the variances in the format of a table representing the probability distribution of the distinct variance values.

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
