Attitudes towards Descriptive Statistics and its Teaching Scale for Mathematics Teachers

Attitudes towards statistics is a topic of interest for researchers and educators, and of special attention when investigating those who will be in charge of transferring this knowledge. This paper examines the reliability and construct validity of the Scale of Attitudes towards the Content of Descriptive Statistics and its Teaching (EAEDE), with two samples: a pilot sample made up of 126 pre-service Chilean and Spanish mathematics teachers; and another with 269 pre-service Chilean mathematics teachers. Following a descriptive-correlational quantitative methodology, we analyze the reliability and construct validity of the EAEDE. The results indicate adequate psychometric characteristics of the scale and, a better fit for the theoretical distribution of the items. This research can be the basis for future analysis on teacher attitudes that require the use of the scale.
