Meta-analysis in ecology, evolution and environmental sciences (METR01)

https://www.prstatistics.com/course/meta-analysis-in-ecology-evolution-and-environmental-sciences-metr01/

This is a ?LIVE COURSE? ? the instructor will be delivering lectures
and coaching attendees through the accompanying computer practical?s
via video link, a good internet connection is essential.

TIME ZONE ? Western European Time +1 ? however all sessions will be
recorded and made available allowing attendees from different time
zones to follow a day behind with an additional 1/2 days support after
the official course finish date (please email
oliverhooker at prstatistics.com for full details or to discuss how we
can accommodate you).

Course overview:
This 5-day course will involve combination of lectures and practical
sessions where students will practice conducting meta-analysis using
the metafor package in R. In addition, students will conduct their own
mini-meta-analyses by working in small groups on an assigned
ecological topic with 8-10 primary research papers provided per topic.
Students would need to decide on effect size metric to use and
inclusion criteria, extract the data from the primary studies, design
the extraction spreadsheet, conduct meta-analysis using the metafor
package and present their results in the form of a PowerPoint
Presentation.

After successfully completing this course students should be able to:

formulate questions for meta-analysis
formulate inclusion criteria for primary studies to be included in the analysis
design spreadsheets for data extraction
conduct literature search on the topic
extract data from published studies
conduct meta-analysis using metafor package in R
present the results of the meta-analysis
