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.

Marguis,

A restaurant offers 5 appetizers that the manager thinks
sell equally well. After looking over the sales for the
previous month, the percentages of sales are:
A publishing company is interested in the number of
books read each year by people. They send out 50
volunteers to conduct research by collecting random
samples of 20 people each and determining the number
of books that group read in the previous year. After
looking at the sample means, the company estimates
that the mean number of books read is 12.4 with a
margin of error of 2.4. Based on these values, what
interval is likely to contain the true mean number of
books read in the previous year by the population?
bruschetta: 17%
pesto bread: 22%
spinach dip: 21%
meatballs: 23%
sampler: 17%
Based on these results, is the manager's thinking
accurate? Explain your reasoning.
