sOL:
Scatterplot to visualize relationship between two numerical varibles

Interaction plot used in ANOVA,Regression,DOE to know whether there are intereaction effects

Parallel lines means there is no interaction

Mosaic plots can be used to visualize the data analyzed in a chi-square goodness-of-fit test

if the blocks are blue in mosiacplot there is a significant relationship

if the blocks are empty in mosiacplot there is no significant relationship

Boxplot we can use to visualize ANOVA

Bar graphs can be used fot t test

Bar graphs can be used to visualize the data analyzed in a 2 sample t-test.

Boxplots can be used to visualize the data analyzed in one-way ANOVA.

An experiment is conducted to test the hypothesis that physical activity (PA) promotes stress resilience. Participants diagnosed with PTSD are grouped as sedentary, low PA, or high PA. They are also grouped, based on their diagnostic evaluations, as having adaptive or maladaptive coping strategies. These data should be analyzed by chi-square test of independence. chi-square goodness of fit test. two-way ANOVA. one-way ANOVA. independent measures t-test.

You have the following statistical tests as choices: some may be used more than once, others not at all.  Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption.

Team SASK is studying distractions while driving. They watched people driving, and recorded any distractions they saw. If someone had more than one distraction, they recorded that fact. They will analyze each distraction separately. For each, they want to know how common each distraction is. * What hypothesis test and/or confidence interval can you use for this? Single-sample t-test One sample proportion test (Chi-square test) Chi-square goodness-of-fit test Two-sample t-test Paired t-test One-way ANOVA Repeated-measures ANOVA Multi-way ANOVA Test for...

Which hypothesis test do I use for this statement? It is believed that the blue team is 3 inches taller than the red team. (for my data, in one column i have their heights and team color in another column) For my null and alternative hypothesis, how do I find those? I was thinking take the difference of the means since we are testing whether one team is 3 inches taller? For example, null is u1-u2= 0, alternative is u1-u2=...
