Final answer:
Option C, which suggests increasing the accuracy of a variance report by decreasing its timeliness, does not cause a variance. This option is a trade-off in report creation, not a cause for differing results.
Step-by-step explanation:
When considering reasons why actual results might differ from standards or expectations, such as in variance analysis, several factors can be the cause. These include:
- Standards not reflecting current economic conditions.
- Unexpected and infrequent events or transactions.
- Inefficiencies in operating conditions.
- Inaccuracies in the accounting system.
Option C, increasing the accuracy of a variance report by decreasing its timeliness, does not represent a reason for a variance to occur. Instead, it reflects a methodological choice regarding the trade-off between accuracy and timeliness when reporting data. Higher accuracy might be achieved with more time, thereby reducing timeliness, but this in itself is not a cause of variance.
