The researcher believes there might be a weak effect from age, but expects a more pronounced effect for different color contrasts. She decides to examine a black on white (B/W) combination compared to 2 alternatives: red on white (R/W) and yellow on blue (Y/B). Here is the data for response times (in milliseconds): Color Scheme B/W R/W Y/B 44 35 19 17 45 7 21 21 33 8 22 23 16-17 32 26 8 24 24 28 20 9 19 21 5 13 47 23 24 15 32 46 37 15 32 39 11 29 Age 18-19 19 24 32 35 16 24 36 13 37 17 19 37 17 41 40 26 26 37 22 19 27 26 29 44 20-21 15 29 29 23 20 44 20 31 18 38 27 41 MAY 12 ...Chrome File Edit View History Bookmarks Profiles Tab Window Help 8 ) 21% Wed 12:41 AM Q ... 45 MyUB - Your personal portal to x Content X Q Lumen OHM X Course Hero x + - -> C a ohm.lumenlearning.com/assess2/?cid=52064&aid=3870880#/skip/103 G TO # F . ..

The last column in the table below is read as, "Partial Eta-squared " and is a concept that was NOT covered in the lectures. Partial n 2 is used when there is a chance the data is not independent (click here to read more if interested ) Computing the values for "Partial 7 2" is not difficult. Simply divide SSeffect by the sum of SSeffect and SSerror. For example, Partial n (A) = SSA /(SSA + SSerror) P-values should be accurate to 4 decimal places and all other values accurate to 3 decimal places Partial Source SS df MS F-ratio P-value Age (A) 2 Color (B) Interaction 4 (A x B) Error 63 Provide the conclusions for this 2-way ANOVA.
