A teacher wanted to investigate if students were more alert in the morning or afternoon using a reading questionnaire with spelling mistakes. She asked students to underline as many errors as possible. Write a one-tailed hypothesis and identify the DV
One tailed hypothesis means directional so potential hypotheses could be:
Students will identify more errors in the morning than in the afternoon
Students will identify more errors in the afternoon than in the morning
The Dv is the measurement taken so in this study it would be the number of errors correctly identified
