The hail events in a certain region are classified by the diameter of the largest hail stone measured in the event: small (0–2 cm), medium (3–5 cm), and large ( > 5 cm). The graph shows the distribution of classifications of all of the hail events in this region over the span of 5 years.

Select from each drop-down menu the option that creates the most accurate statement based on the information provided.
 
Of the years reflected in the graph, the year when this region had the greatest total number of hail events was the year when this region had the greatest number of  GRAPH_1_PLACEHOLDER  hail events and the least number of  GRAPH_2_PLACEHOLDER  hail events.

Of the years reflected in the graph, the year when this region had the greatest total number of hail events was the year when this region had the greatest number of _____ hail events and the least number of ___ hail events.

First we will quickly check which year had the maximum number of hail events.
Year 4 seems to have the maximum so check that first. It has 10 + 4 + 1 = 15 events.
Year 1 has 6 + 3 + 2 = 11 events
Year 2 has 2 more than 11 and year 3 has a similar number too. Year 5 has fewer too.

So year 4 had maximum number of hail events.

This year saw the greatest number of small events (blue bar) and the least number of large events (black bar)
 ANSWER - small, large

1. We are asked to  fill in the blanks , however to do so, we must first  find the year with the greatest total number of hail events .

2. Let's calculate the total number of hail events for all 5 years:

-  Year 1.  Small + Medium + Large  = 6 + 3 + 2 = 11 .
-  Year 2.  Small + Medium + Large  = 6 + 5 + 2 = 13 .
-  Year 3.  Small + Medium + Large  = 5 + 3 + 3 = 11 .
-  Year 4.  Small + Medium + Large  = 10 + 4 + 1 = 15 .
-  Year 5.  Small + Medium + Large  = 7 + 2 + 3 = 12 .

Here, year 4 clearly has the largest amount.

3. During year 4 the greatest amount of hail events were small (10) and the least were large (1).

4. Our answer will be:   D1 - small and D2 - large  .

--------------------------------------

In practice, you can notice how the spike for year 4 (small hail events) is so large and the other two hail events are comparable, so years 1-3 can be ignored. This would mean that only crucial calculations are for years 4 and 5.

Given: 
 
 The hail events in a certain region are classified by the diameter of the largest hail stone measured in the event: small (0–2 cm), medium (3–5 cm), and large (> 5 cm). 
 The graph shows the distribution of classifications of all of the hail events in this region over the span of 5 years. 
 For each year, the total number of hail events is the sum of small, medium, and large.

To Find: 
 
 Blank 1: The type of hail event that was greatest in the year with the greatest total number of hail events. 
 Blank 2: The type of hail event that was least in the year with the greatest total number of hail events.  
 
 Solution: 
First, identify the year with the greatest total number of hail events by comparing the overall height of the stacked bars across all five years.
From the graph, Year 4 has the greatest total number of hail events. Once we have figured this out, the “To find” can be simplified into: 
 
 Blank 1: The type of hail event that was greatest in Year 4. 
 Blank 2: The type of hail event that was least in Year 4.

Blank 1:  Of the years reflected in the graph, the year when this region had the greatest total number of hail events was the year when this region had the greatest number of __________ hail events.

We need to find the kind of hail events that were the greatest in Year 4 among all the 5 years shown. 
 Observe that the blue bar is tallest for Year 4 compared to all other years.

Since blue bars represent small hail events, we can conclude that small hail events were the greatest in Year 4. 
 So, Year 4 was the year when this region had the greatest number of small hail events.

Blank 2:  Of the years reflected in the graph, the year when this region had the greatest total number of hail events was the year when this region had the least number of __________ hail events.

We need to find the kind of hail events that were the least in Year 4 among all the 5 years shown. 
 Observe that the grey bar is shortest for Year 4 compared to all other years.

Since grey bars represent large hail events, we can conclude that large hail events were the least in Year 4. 
 So, Year 4 was the year when this region had the least number of large hail events.
