Thirty students who failed the state writing exam were placed in a class in which they received additional tutoring. After completing the class, all 30 students retook the exam and earned higher scores. Their success was attributed to the effectiveness of class curriculum. Which source of internal invalidity has not been considered

Answers

Answer 1

The source of internal invalidity that has not been considered is "Statistical Regression."

This is because statistical regression as a source of internal invalidity suggests that when the initial study reveals a huge or low extent of the dependent variable, any change tends to show a different result, affecting the study conclusion.

In this case, the researcher can't be definite about the effectiveness of the class curriculum since all the thirty students that failed initially passed the second time.

Hence, in this case, it is concluded that the correct answer is Statistical regression.

what special power does the titular character possess in ""matilda""?

Answers

Answer:

powers

Explanation:

The titular character in Matilda possesses telekinesis. This implies she can control the movement of objects with her thoughts; Matilda only has to focus on an item and instruct it on what to do.

Matilda Wormwood (adoptive name: Matilda Honey) is the title character of the 1988 novel of the same name and the 1996 film version.

These characteristics make Matilda a classic hero: someone that is as ordinary as their classmates yet has one exceptional talent that distinguishes them. Matilda's power, whether through intelligence or telekinesis, is her mind.

Therefore, in Matilda, the main character, telekinesis is present. This suggests Matilda can direct an object's movement with her thoughts; she simply has to concentrate on it and tell it what to do.
