Please show the process with the correct numbers in the formulas 1. In encoding condition A, subjects are asked to name the object encoding condition
Please show the process with the correct numbers in the formulas
1.
In encoding condition A, subjects are asked to name the object encoding condition B, subjects are asked to name the color of each drawing. Then all subjects are tested on their memory. Each subject is randomly assigned to either encoding condition A or encoding condition B.
the researcher hypothesized that condition A (object naming) would lead to significantly better memory compared to condition B (color naming), and she sets the significance level at = .01 for a one-tailed test.
only test ONE condition (either A or B).
Subject ID | Encoding A | Subject ID | Encoding B | |
1 | 77 | 13 | 88 | |
2 | 80 | 14 | 83 | |
3 | 93 | 15 | 81 | |
4 | 78 | 16 | 77 | |
5 | 90 | 17 | 91 | |
6 | 85 | 18 | 90 | |
7 | 91 | 19 | 86 | |
8 | 87 | 20 | 76 | |
9 | 91 | 21 | 88 | |
10 | 90 | 22 | 74 | |
11 | 86 | 23 | 79 | |

A1. Estimated Variance for population:
formula
s2 = [(X-M)^2]/N-1
A2.Calculate the pooled variance (Spooled2) from the two population variances (from question above)
Pooled Variance:
Spooled2 = (df1 / df total) (S1^2) + (df2 / df total)(S2^2)
A3. Use the pooled variance (from question f above) to calculate the variance for sampling distribution 1 (SM12) and the variance for sampling distribution 2 (SM22)
Forumla
SM1^2 = Spooled^2/N1 SM2^2 = Spooled^2/N2
A4. Calculate standard deviation (Sdiffmean)of the comparison distribution
Formula
SDiffMean2 = SM1^2 + SM2^2 OR SDiffMean = SM1^2 + SM2^2
A5 Calculate the t statistic.
[1 point] .5 if the process is correct but the answer is wrong
Formula t = (M-m)/SE *t statistic = t *Sample Mean = M *Population Mean =m *Standard Error (or SD of Sampling Distribution) = SE
please put the numbers in the formula so I can learn this concept and follow along thank you so much
