True or False Questions

If the unit cost remains constant, there is no difference in the value of stock among actual cost, FIFO, LIFO, and weighted average cost methods.?

LIFO is often expressly prohibited, especially when it would artificially reduce tax liabilities.?

Consolidating is the process where small loads from different suppliers are combined to give full vehicle loads for delivery to customers?

The main problems with quantitative forecasts are subjective views and are not as reliable as quantitative methods.?

We should keep an outlier if we can explain the reasons behind it.?

Coefficient of correlation can range from −∞ ??+∞.?

The parameters in exponential smoothing are selected to minimize the sum of errors.?

On a plot of forecast errors, a trend line signals there is a trend not accounted for in the forecast model?

True or False Questions: Determine if true or false. If false why? 1) Premature efforts to treat problem behavior before determining its function can be inefficient, ineffective, and even harmful. 2) Research has found that functional analyses conducted in natural environments (e.g., classroom settings) often yield the same (or even clearer) results compared to those conducted in simulated settings. 3) Problem behavior can only be maintained by one function. Behaviors are not multi-functional. 4) Indirect functional assessment procedures are referred...

True or False Questions A cost driver is a factor, such as machine-hours, beds occupied, computer time, or flight-hours, that causes direct costs. If the overhead rate is computed annually based on the actual costs and activity for the year, the manufacturing overhead assigned to any particular job would not be known until the end of the year. In activity-based costing, all manufacturing costs must be included in product costs. Direct costs are usually included in the costs that are...
