I do agree with Agnes and Mahboob. In addition, there are a number of instances where published data may be used in one's work without a threat to originality. In these circumstances all sources MUST be acknowledged and referenced appropriately.
I undertake systematic reviews and other types of literature reviews. This type of secondary research involves the use of data (that is published data or sometimes unpublished data) mainly from primary studies/sources to collate and synthesize evidence to answer a specific research question. Other types of original work may require the use of published data in statistical or decision analytic models and other types of computations to assess, validate and investigate specific outcomes.
However, I need to say that treating data (published or unpublished) which has been generated by another person as your own is a breach of good practice in the research community.

It is being in practice to use other's data for own research paper provided that the original writer being referred properly in the paper. If you wish to adopt Meta analysis then you need to use others data including yours; alternately straight away you can go for meta analysis by using data of similar kind of studies.
It would be courteous to contact the authors of the data you want to use and let them know your intentions, and, as everyone else has said, you need to cite the source. However, you don't need the authors' permission to use published data.
For your question on use of others' data you have already received interesting answers.
I would like to add that,with proper reference and acknowledgement,you can use the data and analyze it with your own technique and even compare the results with the results of the original author.
After all the Data, once published has come into the Public Domain.
Only thing is, you have to be polite in you claims over the superiority of your work,not belittling the other person's work because that is work that has helped you to carry on the said work further.
I am really happy to see that so many persons like you are bristling with enthusiasm and energy through the Forum of Research Gate,Thanks to the founders of "Research Gate".
I shall come with answers for your other question soon.
When you are so much enthusiastic, as seniors in the field, it is our duty to encourage you and bring out. 'The Best Results' from you.
Carry on with full vigor not getting deterred by any temporary setbacks if at all they occur.
Yes you may use the data with the ethical framework of Research. I have seen some of the pepers which are 90% identical. One should avoid self plagarism as well.
DR Pisupati sir thank you so much for your reply and complements .....as being an undergraduate student and new to research domain i don't know many things many a time its becomes quiet hard to find the answer of some question by my own so its a good platform to know and discuss from other experts .....
It may not be a really bad or good idea. Can you guarantee the authenticity of the data from the paper? Most good papers will not add the data part, though it may be published together with its procedure in "Data in Brief" later. If the paper can get the data, you also can. It is important to use reliable data.
Yes you can, as mentioned in the reply section, within ethical framework (citing the paper). However, you should first view the methodology and/or experimental setup. Simply using the data is not enough. You must make sure you follow accurate published works (vetting of data), for instance:
If the data is based on indoor experiments with equipment that may not be mentioned in the original manuscript then you must ask the author of the manuscript for the material and/or equipment. Moreover, you should ask for uncertainty values (and uncertainty analysis) if not provided in the final manuscript.
If the data is based on outdoor experiments (where many sources of noise and variation may arise) it is necessary to be aware of having your model (physical - mathematical, etc) considering such conditions (with limitation of course). For instance,
The convection of heat from a metal to surrounding environment or variation in wind speed or even the difference in atm based on elevation.
In doing this the data will be much more reliable and useful to you in your work.
