Answer:
missing big data value component from the analysis about the spike could be causality
Step-by-step explanation:
It appears that the missing big data value component from the analysis about the spike could be causality.
The company noticed a spike in online posting about the product, and in response, they increased the amount of paid advertising for that particular product.
However, this increased advertising did not lead to an increase in sales, but instead, sales dropped by 65%.
This suggests that there may be other factors at play beyond just the spike in online posting that the company was not aware of, and that may have contributed to the decrease in sales.
In order to fully understand the situation, the company should conduct further analysis to understand the cause of the spike in online posting and whether or not there is a causal relationship between that spike and the decrease in sales.
