There is a bar chart showing price changes of 4 quarters. And someone asked me does there appear to be a quarterly pattern? I just want to make sure if my understanding is correct about the phrase 'quarterly pattern'. So, does it mean a certain similar/identical pattern or trend among the 4 quarters?
You can only see a quarterly pattern if you can see several years. You can observe that the third quarter is usually the highest, followed by a sharp dip in the fourth. You can observe that the first quarter is usually the weakest. It's hard to see what patterns may emerge, but you can't look at one year's worth of data and say what quarterly pattern appears. Unless the quarters show no variation at all. Then you can say that sales (whatever you're looking at) appear flat from quarter to quarter.
