+# UKDS Safe Researcher Training
+
+May 11th 2020
+
+Case Officer - if want to vary research or pursue new idea with same data, scope creep is OK, can be approved, can need a new project.
+
+## SDC in theory
+
+UKDS/ONS: Threshold = 10 (cell counts)
+
+0 can be a problem unless they are logical - e.g. no 16 year olds have degrees in a table or age x quals
+
+Watch for dominance e.g in % ranks etc
+
+Avoid min/max -> unless have 10 cases (rounding?) Do you need to publish this?
+
+Beware secondary disclosure - e.g. subtract 1 table counts from another -> do you get small cell counts?
+
+## SDC & research
+
+Descriptive tables are a pain - inherently high risk
+
+Regression coeffs etc are easier
+
+No automated output checker
+
+Avoid skewed distributions, small numbers, huge outliers, dominant observations, rare events etc
+
+Avoid min/max values unless can prove not identifiable. Same for median (which is on a box plot)
+
+If asked for new details etc always add these to the outputs - never in an email
+
+Raise/notify an issue early
+
+## Output checking
+
+At end of project ask for output which is syntax files & they will send
+
+All sessions are recorded - can be used to resolve issues etc
+
+Always include underlying counts for Figures (unweighted)
+
+Beware summary tables which include all units and then categorised tables which leave out a row/cell with 1 item in it.
+
+Maps - use heat maps -> intensity/prevalence, much safer. Not point maps.
+
+Put yourself in checker's position! Make it easy.
+
+'Good' output:
+
+use https://www.ukdataservice.ac.uk/help/get-in-touch.aspx
+
+-> output request
+
+- publishable quality output (word & excel tables?)
+- doesn't support knitr etc - does SERL portal?
+
