Fig. 5: The Wright map of SE items, displaying the difficulty of endorsing each item on a logit scale.

From: Rasch analysis in developing a questionnaire to measure self-efficacy beliefs of Omani preservice science teachers for teaching through engineering design

Fig. 5

The y-axis represents the logit values, ranging from −0.75 to 0.75, with positive values indicating items that are harder to endorse (e.g., harder to select ‘Strongly Agree’) and negative values indicating items that are easier to endorse (e.g., easier to select ‘Strongly Agree’). Items are plotted as a function of item measure, with each item labeled as ‘Q’ followed by its number (e.g., Q1, Q2) and positioned along the logit scale according to its difficulty. Q1 is shown as the hardest to endorse, while Q2 is the easiest.
