The illustration under represents the depth of snow in centimeters at a certain ski resort in Canada over 3 years.
Overall, looking at the graph, we can see that November to January has the lowest snow size in all three years; however, there is a significant jump from January to February that remains almost constant until April, with minimal differences in average between months.
Average length in ski resorts in Canada during the first months (between nov and jan) are approximately between 100-200 cm, where the third year is leading in all months, which stays at 150-200cm, but the first year has almost the same numbers with almost no differences. At the same time, the second year stays the lowest, even with the highest result smaller than 150, and the least with 50cm.
However, the last months that start from feb and end in apr with all years, have an enormous jump from 200 that doubles to 500. Even though it has significant changes month has gaps too, while last year stays in the last place with a range of 300-350, the first two years have almost the same depth, from 450-500, which takes advantage of a minimum of 100cm. Surprisingly, Febb and Mar have the exact size with no difference at all across all years.
