These components confirm the specific time frame the data represents, making the report a fixed reference that does not change with subsequent data updates or accesses.
This is crucial for accurate historical analysis and for maintaining the integrity of the data as it was at the time of the report's creation.

NEW QUESTION # 136
Given the following graph:
Which of the following summary statements upholds integrity in data reporting?
- A. Sales are approximately equal for Product A and Product B across all strategies.
- B. Product D should be promoted more than the other products in all strategies.
- C. While Strategy 2 does not result in the highest sales of Product D, over all products it appears to be the most effective.
- D. Strategy 4 provides the best sales in comparison to other strategies.
Answer: D
Explanation:
Strategy 4 provides the best sales in comparison to other strategies. This is because the total sales for Strategy
4 are the highest among all the strategies, as shown by the black line. The other statements are not accurate or do not uphold integrity in data reporting. Here is why:
Statement A is false because sales are not approximately equal for Product A and Product B across all strategies. For example, in Strategy 1, Product A has more sales than Product B, while in Strategy 3, Product B has more sales than Product A.
Statement C is misleading because it does not account for the difference in scale between the products. While Strategy 2 has the highest total sales among all products, it does not necessarily mean that it is the most effective for each product. For instance, Product D has very low sales in Strategy 2 compared to other strategies.
Statement D is biased because it does not provide any evidence or justification for why Product D should be promoted more than the other products in all strategies. It also ignores the fact that Product D has the lowest sales among all products in most of the strategies.
NEW QUESTION # 137
Five dogs have the following heights in millimeters:
300,430, 170, 470, 600
Which of the following is the standard deviation for the five dogs?
- A. 154mm
- B. 21,704mm
- C. 394 mm
- D. 147mm
Answer: A
Explanation:
The correct answer is B. 154 mm.
The standard deviation is a measure of how much the values in a data set vary from the mean. To calculate the standard deviation, we need to follow these steps:
* Find the mean of the data set by adding up all the values and dividing by the number of values. In this case, the mean is (300 + 430 + 170 + 470 + 600) / 5 = 394 mm.
* Find the difference between each value and the mean, and square it. In this case, the differences and their squares are:
* 300 - 394 = -94, (-94)
