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.

Question

100%

Keep getting the test statistic wrong.

You wish to test the following claim $(H_a)$ at a significance level of $\alpha = 0.01$.

\[
H_o: \mu = 50.5
\]
\[
H_a: \mu < 50.5
\]

You believe the population is normally distributed, but you do not know the standard deviation. You obtain a sample of size $n = 661$ with mean $\bar{x} = 49.2$ and a standard deviation of $s = 9.2$.

**What is the test statistic for this sample?**
(Report answer accurate to three decimal places.)
test statistic = $-3.71 \, \text{❌}$

**What is the p-value for this sample?**
(Report answer accurate to four decimal places.)
p-value = $0.0002 \, \text{✅}$

A psychologist wanted to examine whether regular mindfulness practice would have an effect on the anxiety levels of her clients. She randomly assigned her clients into two groups. She asked the first group to meditate every day for 15 minutes for 6 months in addition to their regular counseling sessions. In the second group, she continued her regular counseling sessions without any extra treatment. Since the psychologist does not know how to run the analysis, your task is, by using your statistics skills, to inform her whether the mindfulness practice has made a difference in the lives of her clients and in what sense. To provide her with an answer, I want you to run two different tests: An Independent Samples t-test and a One-Way ANOVA, report their results, and compare the findings of these two analyses.
