EXPERIMENTAL DESIGN AND ERROR ANALYSIS

$($a$)$ Discuss how you understand the concepts of Experimental Design and Experimental Research.

$($b$)$ What are the two requirements of a good experimental design?

The data in Table $1$ shows vitamin D retention at a temperature of $20C.$

Table $1$ Vitamin D retention at a temperature of $20C$

$\backslash$table$[[$Temp of $20\backslash$deg C$],[$Storage days,Trial $1,$Trial $2,$Trial $3],[5,95,88,87],[10,87,78,84],[15,76,65,73],[20,65,64,59],[25,45,55,48]]$

$($c$)$ Construct bar charts for the data in Table $1$

$($d$)$ Determine the mean and standard deviation values for the data

$($e$)$ Using the above data, add the appropriate error bars on the bar plots

$($f$)$ Analyse and interpret the results.
