Could somebody help me with the step by step solution of ANOVA without using excel?
Psychopaths display a constellation of traits that render them a dangerous group of individuals. While psychopaths live among us, many can be found within the criminal justice system. In fact, many have a history of violent behavior in general, and sexual aggression in particular. Some research has suggested that psychopaths have difficulty distinguishing the emotions displayed in facial expressions and also attribute hostile intentions to innocuous situations. These patterns have been thought to contribute to the violence psychopaths display. In this study, the researcher presents a short video clip of a person describing a situation that is either innocuous or aggressive while displaying either a fearful or angry facial expression. Twenty psychopaths (n=20) are recruited to participate and are asked to identify their response by selecting it on the computer screen. Their response time (in seconds) is being measured in order to determine if psychopaths respond differently depending on the type of scene and the emotion being displayed. Test this hypothesis at an alpha at 0.05 and use all of the steps of hypothesis testing.
ANSWER !- The hypothesis being lest is Ho : There is no main effect of the type of scene Ha : There is a main Effect of the type of Scene The test statistic , F : 72.25 The P-Value is 010000 . Since the p-value (0.0000 ) is lon than the significance Level (or05 ) , we Can reject the null hypothesis . Therefore , we Can Conclude that there is a main effect of the type of scene The hypothesis being tested is : Ho : - There is no main Effect of the Emotion being displayed Ha : There is a main Effect of the Emotion being displayed The test statistic , f = 61-36 The P- value is 0.0000Since the p-value (0.0000 ) is lon than the Significance level (0.05 ) , we can reject the null hypothesis . There-fore , we can Conclude that there is a main Effect of the Emotion being displayed - The hypothesis bing tested is : Ho: There is no interaction Effect Ha: There is an interaction Effect -The test statistic , F: 56-25 - The P-Value is 010000 Since the p-value (0.0000 ) is less than the Significance level ( 0.05 ) , we can reject the null hypothesis. There fore , we Can Conclude that there is an interaction effet Working : ( Two-fac-los ANOVA ) Excel steps : Enter the data in Excel-ANGER FEAR Innocuous 16 15 17 13 1 4 Aggressive Go to Data > Magastat.
