Answer:

split-half reliability

Split-half testing measures reliability. In split-half reliability, a test for a single knowledge area is split into two parts and then both parts given to one group of students at the same time. The scores from both parts of the test are correlated. This is what the researcher did.

Answer:

the researcher is measuring the deviation in the results

Explanation:

The deviation of a statistical result shows how far results depart from the center of the measurement. In other words, the results show how the measurements depart from the mean or average value. By taking the measurement values, the upper limit can be established. Next, the lower limit of the results can be measured. Next, the standard deviation can be measured to determine the nearness of furtherness of the values from the control values. Then, a plot of the standard deviation against the results can be plotted.

When comparing the direct write-off and allowance methods, which of the following statements applies to the allowance method? a.
Luba_88 [7]

Answer:

c.The result is based on either a percentage of sales or an analysis of receivables

Explanation:

Generally, companies will choose between two approaches under the allowance method.

Percentage of Sales:  Using historical data, a company examines the relationship between sales and uncollectible accounts receivable.  If there is a fairly stable relationship between the two, a company will use the historical Uncollectible Accounts / Credit Sales ratio to estimate the bad debts expense in the current period.

This method is sometimes referred to as the income statement approach.

Percentage of Accounts Receivable:  Using historical data, a company examines the relationship between accounts receivable and uncollectible accounts.  Companies will oftentimes increase the accuracy of these estimates by looking at their aging schedule for patterns, rather than using a composite (or total) of their receivables

This method is sometimes referred to as the balance sheet approach
