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.

True/false: Some researchers have suggested that blood pressure may tend to be higher on average when measured on a subject's right arm than on their left arm. A doctor decided to investigate this conjecture by taking readings of the systolic blood pressure on both arms of a random selection of twelve patients at his practice. A paired samples t-test can be applied.

In 2019 Chicago Hope Hospital hired new nurses from two top universities in the country. After one year, the hospital conducts a simple study to analyse whether there is a significant difference in regard to the performance of the nurses who graduated from the two universities. Considering the maximum performance score of 100, the following is the result of independent sampling of the nurses’ performance scores. Assume the scores are not normally distributed.
