Linda is developing a new test to assess general cognitive functioning. She finds a significant correlation of r = .72 between her new test and the Montreal Cognitive Assessment, an existing measure of general cognitive functioning. Which of the following types of validity does this provide support for?

Group of answer choices

Face or content validity

Criterion validity

Convergent validity

Divergent validity

This provides evidence for a type of reliability, not validity

Expert Solution

Answer:-

Given That:-

Linda is developing a new test to assess general cognitive functioning. She finds a significant correlation of r = .72 between her new test and the Montreal Cognitive Assessment, an existing measure of general cognitive functioning. Which of the following types of validity does this provide support for?

Group of answer choices

Face or content validity

Criterion validity

Convergent validity

Divergent validity

This provides evidence for a type of reliability, not validity

Given,

Summerized the information given in the question Helen is developing a new test to assess-----

The correct answer is option Criterion validity

Explanation:-

Comparing the test with an established measure is criterion validity. In this research, the investigator finds a significant correlation of r = 0.72 between his new test and the montreal cognitive assesment, an existing measure of general cognitive functioning.

This provides evidence for a type of reliability, not validity because by comparing with established measure, the investigator establishes the consistency of his test. But he has not established the cauuracy of his test.

To test the effects of cartoons on cognitive functioning, a researcher assigns 15 children to watch 30 minutes of Spongebob Squarepants, 15 children to watch 30 minutes Looney Tunes, and 15 more children to color for 30 minutes. The research then tests both children on the same cognitive functioning task." A) One sample chi-square B) Independent samples t test C) Paired samples t test D) One way ANOVA E) Repeated Measures ANOVA

A scientist finds a new acid which she knows is diprotic. She only has a solution which is 0.1000 in this diprotic acid H2Acid and she only has 50.00mL of it. She decides she must find out what the pKa1 and pKa2 is for the diprotic acid. She has a pH meter which has been calibrated and a 0.1000M NaOH solution. Making only two pH measurements, how would she estimate pKa1 and pKa2. Please be specific about your answer. Which...

Imagine that a researcher is conducting a paired-samples t test. She finds that the sample mean difference is 3.665, the standard deviation of the difference scores is 9.334, and the sample size is 75. The researcher is also using a typical null hypothesis that proposes no differences between the relevant population means. Under these circumstances, what is the value of Cohen's d? Please retain a minimum of three decimal places for all steps (if relevant) and provide a minimum of...

A worker is given monthly tests (new test generated each month) to assess his ability to be effective in the workplace. However this worker got into an accident recently. The employer said that "the accident would change them, and the employer believe that the worker is a completely different person before versus after the accident. The employer would like to determine if the worker's performance has significantly changed since the accident has occured. alpha = 5% before = sample 1...

A farmer wishes to test the effects of a new fertilizer on her tomato yield. She has four equal-sized plots of land-- one with sandy soil, one with rocky soil, one with clay-rich soil, and one with average soil. She divides each of the four plots into three equal-sized portions and randomly labels them A, B, and C. The four A portions of land are treated with her old fertilizer. The four B portions are treated with the new fertilizer,...

When examining the relation between two variables, when is it better to use the regression coefficient β (beta) instead of the correlation coefficient r to test for significant effects?

Answer the questions below based on the following table: Fatigue Vigor Sleepiness Tension .36* –.31* .08 Fatigue –.73*** .57** Vigor –.49** * p < .05, ** p < .01, *** p < .001 The strongest correlation is between _________________________ and ________________________. (Give variable names) The weakest correlation is between __________________________ and ________________________. (Give variable names) The correlation between sleepiness and fatigue is ___________________ (indicate direction) and ________________________ (indicate strength). 1.
