Hello po sir salamat po dito sa part 2.
Ask ko lng po sana:
Starting 6:37 about dependent samples t-test or wilcoxon, if usually ay ginagamit po ito for experimental researches na within, pwede din bang gamitin ito for comparative studies like SHS students perception on online classes vs. face to face? Same students po pero 2 survey instruments ang sasagutan (1 for online perception and 1 for face to face). Magfa-fall ba yung case sa (non-)independence kung the performance of student A in survey A is independent from the performance of student B in survey B?
TIA sa kasagutan. More videos po like this. Thanks po ulit😊😊😊

Key Timestamp Personal Notes:
5:35 - Mann-Whitney U Test and Independent T-Test (used for comparing two separate groups on a certain variable or multiple values ata. Kunwari 3 values - X,Y,Z so those two groups itetest kada X,Y,Z)
6:26 - dependent samples T-Test (same na tao pero 2 scores only)
7:23 - One-Way ANOVA (comparing multiple groups for a certain outcome variable)
8:12 - Friedman Test and One-Way Repeated Measures ANOVA (similar logic to dependent/paired T-Test. At least 3 pero pwde din 2 kaya lang madalas at least 3 or more scores sa iisang group. Example: One Group pero scores chineck sa 1st, 2nd, 3rd, at 4th Qrtr.)
9:25 - Pearson-r (ginagamit pag correlate 2 continuous variables) - cannot be used if ordinal

Attitude of students is usually measured as Very positive to very negative wherein we rank them from 5 to 1. Do we consider the data as ordinal and use the non-parametric test?
