The answer will depend on the location and ages of the students.
Frequency is how often something occurs. Frequency distribution is how often something occurs within a group of separate categories or ranges. Say you had a list of exam scores from a class of students. You might want to find out how many people got between 0% and 10%, how many got between 11% and 20%, how many got between 21% and 30%, and so on. All you are interested in is the how many as compared to who actually got the scores. What you would be doing is creating a frequency distribution table. You would be finding out how many people got results in the various ranges, or how the frequency of results are distributed across these ranges.

Some common challenges students face when solving Doppler effect problems include understanding the concept of frequency shift, correctly applying the formula for calculating the observed frequency, and accounting for the relative motion of the source and observer. Additionally, students may struggle with interpreting the direction of the frequency shift based on the motion of the source and observer.
