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.

Expert Solution

Step 1

Given : Compute weighted average for waiting 50% texts , 30% quizzes , 20% projects . Scores for each is provided .

Find average for texts scores :

$M e a n = \frac{92 + 87 + 67}{3} = \frac{246}{3} = 82$

Find average for quizzes scores :

$M e a n = \frac{75 + 89 + 100 + 92 + 95}{5} = \frac{451}{5} = 90.2$

Find average for projects scores :

$M e a n = \frac{100 + 85 + 92.5}{3} = \frac{277.5}{3} = 92.5$
