Question

salads a restaurant is tracking how many salads it sells each week.

is there a correlation between the variables in the data? is there likely causation?

a) correlation but no causation

b) positive correlation and causation

c) negative correlation and causation

d) neither correlation nor causation

Explanation:

Step1: Analyze the data trend

Looking at the number of Garden Salads and Caesar Salads sold each week, as the week number increases, both the number of Garden Salads (14, 16, 17, 20, 21) and Caesar Salads (21, 23, 24, 24, 26) generally increase. So there is a positive correlation.

Step2: Check for causation

Just because the number of both salads sold is increasing over time (with the week number), there is no inherent cause - effect relationship between the two types of salads. For example, it could be due to overall increased business at the restaurant, better marketing in general, etc., not because one salad type's sales cause the other's.

Answer:

A. correlation but no causation
