Hello, i have doubt in counting mean of frequency and consumption of a food group.
For instance, fritters group consisted of french fries and sausages. I gather the frequency (how often they eat in a week) and consumption (portion in size) of that food. All data are presented as numeric data. If a person only eat french fries, i input the frequency and consumption of sausages as zero. If i want to know the mean of frequency and consumption from fritters group, should i add the average of french fries + average of sausages or how? thank you
