Statistics on TEM

1. Let’s practice TEM

2. Criteria of scientificity

• Falsifiability (Popper’s criteria)
• Reproducibility
• Reproducibility in different laboratory/by different scientist
Karl Popper
1902-1994

3. How to collect, analyze and present TEM data

• To get a reliable standard deviation, measure a large number of
particles (typically >300) to ensure the sample accurately
represents the whole sample set.
• Pair the standard deviation with the mean (e.g., "15.4±2.1 nm")
and clearly state the total particle count (
