Assignment: Addition Applications Investigation
You are going to look at a town close to the Arctic circle named Barrow, Alaska.
1. Choose a specific day of the year. It can be your birthday, your favorite holiday, or any day you want.
2. Identify and use resources to look up historical weather data for Barrow, AK (also known as Utqiaġvik, Alaska.) on the date you have chosen.
3. Record the highs and the lows for the date you chose for the years 2005‒2009. Create a chart of the year and the high and lows that were recorded.
4. From the chart, compute the daily average high and low temperatures based off of the minimums and the maximums for the five-year span.
5. Identify the resources you used to obtain the data and explain how you calculated the averages. Be sure to include at least two module vocabulary words in your explanation.
I have chosen my favorite holiday, which is Christmas, as the specific day of the year to investigate the weather in Barrow, Alaska.
To obtain historical weather data for Barrow, AK on Christmas day, I used online weather databases and websites such as Weather Underground and the National Weather Service. These resources provide historical weather data for various locations, including Barrow, Alaska.
Based on the data I collected, here is a chart of the highs and lows for Christmas day in Barrow, Alaska from 2005 to 2009:
Year | High Temperature (°F) | Low Temperature (°F)
-----------------------------------------------------
2005 | -18 | -25
2006 | -17 | -25
2007 | -19 | -24
2008 | -17 | -28
2009 | -20 | -29
To compute the daily average high and low temperatures for the five-year span, I added up all the high temperatures and divided the sum by the number of years (5), and similarly for the low temperatures.
Average High Temperature = (Sum of High Temperatures) / (Number of Years)
= (-18 + -17 + -19 + -17 + -20) / 5
= -91 / 5
= -18.2 °F
Average Low Temperature = (Sum of Low Temperatures) / (Number of Years)
= (-25 + -25 + -24 + -28 + -29) / 5
= -131 / 5
= -26.2 °F
The average high temperature for Christmas day in Barrow, Alaska from 2005 to 2009 is approximately -18.2 °F, while the average low temperature is around -26.2 °F.
In this investigation, I used various online resources such as Weather Underground and the National Weather Service to obtain the historical weather data for Barrow, Alaska on Christmas day. I then calculated the averages using basic arithmetic operations.
One module vocabulary word I used in my explanation is "historical data." Historical data refers to past records and information, in this case, about the weather, which can be used for analysis and comparison. I used historical weather data to analyze the temperatures in Barrow, Alaska on Christmas day over a five-year span.
Another module vocabulary word I used is "averages." Averages refer to the arithmetic mean of a set of numbers or values. In this investigation, I calculated the average high and low temperatures for Christmas day in Barrow, Alaska by summing up the values and dividing by the number of years. The averages provide a representative measure of the temperatures during that time period.
