DA0-002 Data Analysis Practice Question
A data analyst needs to identify the most frequently occurring value in a dataset. Which measure of central tendency should they use?
⚠ Common exam trap
It's easy for candidates to confuse 'most frequently occurring' with 'average' or 'middle value' and incorrectly choose mean or median, especially when the dataset is numeric and they assume central tendency always refers to mean.
