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

Can you please help and check my answers!

In calculating $ S(M_1 - M_2) $, you typically first need to calculate $ s^2_p $. $ S(M_1 - M_2) $ is the value used in the denominator of the t statistic for the independent-measures t test.

Suppose you conduct a study using an independent-measures research design, and you intend to use the independent-measures t test to test whether the means of the two independent populations are the same. The following is a table of the information you gather. Fill in any missing values.

\[
\begin{array}{|c|c|c|c|c|c|}

& \text{Sample Size} & \text{Degrees of Freedom} & \text{Sample Mean} & \text{Standard Deviation} & \text{Sums of Squares} \\
\hline
\text{Sample 1} & n_1 = 41 & df_1 = 40 & M_1 = 14.3 & s_1 = 8.2 & SS_1 = 2,689.6 \\
\text{Sample 2} & n_2 = 21 & df_2 = 20 & M_2 = 13.6 & s_2 = 6.8 & SS_2 = 924.8 \\

The pooled variance for your study is $ 60.240 $. (Note: You are being asked for this value to three decimal places, because you will need to use it in succeeding calculations. For the most accurate results, retain these three decimal places throughout the calculations.)

The estimated standard error of the difference in sample means for your study is $ 2.083 $.

The t statistic for your independent-measures t test, when the null hypothesis is that the two population means are the same, is $ 0.34 $.

The degrees of freedom for this t statistic is $ 60 $.

For the independent-measures t test, which of the following describes the pooled variance (whose symbol is $ s_p^2 $)?

- Ⓣ An estimate of the standard distance between the difference in sample means ($ M_1 - M_2 $) and the difference in the corresponding population means ($ \mu_1 - \mu_2 $)
- ☐ The variance across all the data values when both samples are pooled together
- ☐ The difference between the standard deviations of the two samples
- ☐ A weighted average of the two sample variances (weighted by the sample sizes)
