Answer and Explanation:
Some of the advantages of using the F measure (weighted harmonic mean) over using the Precision & Recall when evaluating an IR system performance are as follows-
- Precision quantifies the number of positive class predictions that actually belong to the positive class.
- Recall quantifies the number of positive class predictions made out of all positive examples in the dataset.
- F-Measure provides a single score that balances both the concerns of precision and recall in one number.
- A measure that combines precision and recall is the harmonic mean of precision and recall, the traditional F-measure or balanced F-score:
F=2((precision.recall)/(precision+recall))
Answer:
The answer is "check the worksheet is not read only"
Explanation:
The read only mode is used for read the file data, and it doesn't allows the user to update the file, and for updating the worksheet we should check iut does not open in the read-only mode.
If it is open, then we close it and for close we goto the office button and click on the tools option after that goto general setting, in this there is a check box for turn off the read-only mode.
