+- How do you write a lesson using R Markdown and `{sandpaper}`?

+- Explain how to use markdown with the new lesson template
+- Demonstrate how to include pieces of code, figures, and nested challenge blocks

+## And the purpose of statistics
+
+
+Statistics is the science of collecting, summarizing, presenting and interpreting data, and of using them to estimate the magnitude of associations and test hypotheses. It has a central role in medical investigations” 
+
+Typer af data
+
+kumulativ fordelingsfunktion - graf -> 25%, 50% og 75% kvantiler
+
+Og så kan vi jo også beregne en 5% kvantil - der hvor 5% af observationerne er
+mindre (og 95% er større)
+
+Hvordan beregner vi middelværdi?
+
+Hvorda beregner vi spredning/standardafvigelse
+
+Hvordan med variansen?
+
+Hvordan ville vi egentlig sige noget om variationen i data? 
+
+-> forskellen på alle observationerne og middelværdien.
+
+-> kvadreret
+-> men det giver noget snask i enhederne
+-> så vi tager kvadratroden.
+
+Herfra videre til normalfordelingen
