Feliciano is using a pretest/posttest design to conduct an experiment on improving children’s handwriting, employing two different techniques of improving handwriting and a control condition. In the results, the two groups who receive the treatment don’t show any difference from each other. Feliciano believes that there is a difference but that his 3-point assessment scale of handwriting cannot detect it. Identify the true and false statements about Feliciano’s study. True Statement(s) Drag appropriate answer(s) here Feliciano is most concerned about using an insensitive measure. Press Space to open To address his concern, Feliciano should use a scale with more levels for his dependent variable. Press Space to open To address his concern, Feliciano should use a manipulation check for his independent variable. Press Space to open To address his concern, Feliciano should increase his sample size. Press Space to open Feliciano is most concerned about measurement error.

Respuesta :

The test result can be made more responsive by adjusting the parameters

of the test.

  • Feliciano should use a scale with more levels for his dependent variable
  • Feliciano should use a manipulation check for his independent variable
  • Feliciano should increase the sample size.

Reasons:

The type of experiment being performed by Feliciano is children

handwriting improvement based on two techniques and a control condition.

The number of groups that receive the treatment = Two

The assessment method used = 3-point assessment scale

The true statements are;

  • Feliciano should use a scale with more levels for his dependent variable

Increasing the number of levels on the scale, increases the variability of the response such that more responses can be obtained from the participants than when using a 3-point scale, based on the closeness between the the variables being assed.

  • Feliciano should use a manipulation check for his independent variable

A manipulation check can be used to determine the effectiveness of the treatment applied , such as the inclusion of question that finds out about the participants association to the treatment.

  • Feliciano should increase the sample size

Increasing the sample size increases the z-value, and makes it more likely to reject the null hypothesis, that there is no difference between the two groups.
