Many-Facet Rasch Measurement Using Facets Software

In this video, I demonstrate how to carry out a Many-Facet Rasch Measurement Using Facets Software. If you have not watched the previous videos on Rasch measurement, they can be found from the links below: 1. https://www.youtube.com/watch?v=FDUYm7ZhXkw&t=49s 2. https://www.youtube.com/watch?v=X4EtIJlPBTU 3. https://www.youtube.com/watch?v=2PgOxMy54iQ 4. https://www.youtube.com/watch?v=OIhWWVzvNa0 Videos on reliability and Cohen's Kappa: 1. Reliability 1: External reliability and rater reliability and agreement (18:48) https://www.youtube.com/watch?v=erehShKTJR0&t=760s 2. Reliability 2: Cronbach's alpha and internal reliability (14:19) https://www.youtube.com/watch?v=scsPvCSq6SE&t=392s Reliability 3: Cronbach's alpha and internal reliability (10:44) 3. https://www.youtube.com/watch?v=uDexRw2w-hk Reliability 4: Cohen's Kappa and inter-rater agreement (18:25) 4. https://www.youtube.com/watch?v=djd7GalIB8c&t=6s The specification of Facets input file is as follows: Title = FACETS Speaking performance Facets = 3 ; student + rater + item inter-rater=2 ; compute inter-rater agreements (Inter-rater = rater facet number) Positive = 1 ; the first facet has positive ability Noncentered= 1 ; measure from the center of the measures for each facet Models= ?,?,#,R5 ; put the model statement for your facets and elements here. * Labels= * 1, students 1-74 * 2, raters 1=A 2=B * 3, items 1-20 * data= For partial credit model, use a #, for example: ?,?,#,R5 Download Facets from: https://www.winsteps.com/minifac.htm Relevant Facets-based papers: 1. https://www.tandfonline.com/doi/full/10.1080/15434303.2015.1133626 2. https://www.tandfonline.com/doi/full/10.1080/15434303.2017.1393820 3. https://www.tandfonline.com/doi/full/10.1080/10627197.2015.1061989
