In the academic world, students and their faculty supervisors often collaborate on research papers, producing works in which publication credit can take several forms. Many feel that the first authorship of a student's paper should be given to the student unless the input from the faculty advisor was substantial. In an attempt to see whether this is in fact the case, authorship credit was studied for several different levels of faculty input and two objectives (dissertations versus nondegree research). The frequency of authorship assignment decisions for published dissertations is given in the accompanying tables as assigned by 60 faculty members and 161 students. Faculty respondents High Input Medium Ingut Low Input Faculty first author, student mandatory second author Student fiest author, faculty mandatory second author 18 Student first author, faculty courtesy 20 High Ingut Medium Ingput Low Input Facuity first author student mandatory 21 Student Rirst author, faculty mandatory Student first author, faculty courtesy second author Student sole author 30 (a) Is there sufficient evidence to indicate a dependence between the authorship assignment and the input of the faculty advisor as judged by faculty members?

Answer 1

Answer #1

The expected values are computed in terms of row and column totals. In fact, the formula is Ei where R corresponds to the tot

Squared Distances Column1 Column 2 0-1.4671.467 0.364 567 2.912 (3-3,6670.121 Column 3 0-0.8 0.8 Row 1 18-131.923 3-6 Row 2 4

Test Statistics The Chi-Squared statistic is computed as follows: X2 0%-Gr 2.964-1.923 + 3.51 + 1.256 + 1.467 + 0.364 + 2.912

p - value = The P-Value is .001481.

conclusion-

Option b) is correct.
