How do you bring the hardness up in a pool?

To increase the hardness in a pool, you can add calcium chloride or calcium carbonate, which are commonly used chemicals. Before adding, test the water to determine the current calcium hardness level and calculate how much product is needed to reach the desired level, typically between 200-400 ppm. It's important to dissolve the chemicals in a bucket of water before adding them to the pool to ensure even distribution. After adding, run the pump for a few hours and retest the hardness levels to ensure they are within the desired range.


What are the psychometric properties of the BASC-2?

The Behavior Assessment System for Children, Second Edition (BASC-2) has good reliability, validity, and standardization properties. It includes measures of internal consistency, test-retest reliability, convergent and divergent validity, and factor structure. It also has strong norms based on a large sample size to provide accurate comparisons for interpretive purposes.


Explain the process you would go through to make your instrument valid and reliable?

To ensure validity, I would review the instrument's content to ensure it aligns with the construct being measured. For reliability, I would conduct a pilot test to assess consistency in measurements over time and among different raters. I would also use statistical analyses, such as Cronbach's alpha for internal consistency or test-retest reliability, to further assess the instrument's reliability.

Yes, you can request a retest if you believe the initial drug test result is inaccurate. It's important to communicate your concerns to the testing authority or your employer, as they may have procedures in place for retesting or reviewing results. Additionally, you might want to consider providing evidence or context that supports your claim. However, the decision to conduct a retest ultimately depends on the policies of the organization involved.
