Project + Research Question

Use Choice recommended titles as checklist for our chemistry monograph collection.

Do the recommended Choice chemistry monograph titles circulate any more than the chemistry monograph collection as a whole.

A Little Background

84% of monographs are acquired via our approvalplan (including DDA)

Choice Titles and Circulation

Some studies found a relationship between Choice titles and circulation, while others did not.

Methodology (Approach)

Choice Titles vs. Collection

Hypothesis Testing Ho: Mean circulation of the two populations

is the same (u1=u2)

H1: Mean circulation of the two populations is different (u1≠u2)

Percentage of Titles Circulated

Methodology (Data)

General Chemistry Collection Titles (“Non-Choice” Titles)

Choice Chemistry Titles

Circulation Data

Results (Titles)

Choice RecommendedChemistry Titles*

Chemistry Collection 2,525 titles

* 436 total, 404 recommended, and 397 cataloged at Texas A&M as QDs.

Results (Circulation)

t-test resulted in a p-value of 0.0063,so the null hypothesis is rejected.

Circulation: Choice Titles versus General Chemistry Collection

The mean circulation for Choice titlesand the Collection is different!

Percentage of Titles Circulated

Discussion and

Conclusion

Mean circulation was skewed, so comparison of the median may be more representative.

On a percentage basis Choice chemistry titles circulated more than the general chemistry collection.

The print chemistry monographs available both in print and online circulated as much as print only.
