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.

A researcher is conducting a test to see if handedness (right or left) affects the speed at which people perform a particular task. The researcher only knows the order in which the contestants finished. When the data are summarized (with R for right-handed and L for left-handed) the order of finishing (fastest to slowest) was: R, R, R, R, L, R, L, R, L, L Is there statistically significant evidence of an effect of handedness on the speed? Test statistic: The name of the statistical table, degrees of freedom (if appropriate), and the numerical value of the critical value for this test: P-value: Circle an appropriate conclusion: • There is significant evidence that left-handed contestants will finish the task faster. • We cannot reject the hypothesis that handedness has no effect on the time to finish the task. • There is significant evidence that right-handed contestants will finish the task faster.
