No. You will need to submit a completely new application but do not have to pay the application fee.
No, the DPhil in Statistics is not currently offered as a part-time course.
In exceptional circumstances the start can be delayed. It is discouraged though as you would miss the induction events which happen in October and help students settle into Oxford.
The proposal should make it clear which area of probability and statistics you would like to work in. If you have a clear idea about what you would like to research, then you should detail that in the project proposal. It is very common not to have a firm project in mind when applying. In that case a paragraph or two about what you find exciting is completely sufficient.
The number changes from year to year and indeed during the year. Typically about 6 students per year will have full funding from Oxford, but that number is highly variable. Usually we only have one place for overseas students available. You can find other funding opportunities at http://www.ox.ac.uk/admissions/graduate/fees-and-funding/graduate-scholarships
If you are looking into other funding opportunities then you should make sure that you make their deadlines, which may be before the end of 2018. In that case you should apply for the 16 November 2018 deadline. Oxford funding is mostly assigned in February/March 2019, and in that process all completed applications received by the 25 January 2019 deadline will be considered.
Yes, we are happy to offer Skype interviews to all candidates who are selected to interviews.
There will be interviews in December 2018 and February 2019. The dates are yet to be confirmed.
The processing of applications takes about two weeks from the application deadlines (16 November 2018, 25 January 2019, 1 March 2019), so you are unlikely to hear from us until two weeks after the application deadline. Depending on availability you may only hear from us a few days before the interview days. For interviews we would contact you so that we can arrange a time which works for you.
Doctoral students who suspend for maternity leave are entitled to 26 weeks paid leave regardless of their current funding situation at the research council stipend level. In those cases where both the mother and father are students, this financial support can be shared if it enables the female student to return to study in the department. Funding is available for students in years 1-4 of their programme.
