a)Rainfall v. Month (Seattle)
b) What is the change in rainfall from January to different months of the year in seattle?
c)
| Month | Rainfall (in) |
| January | 5.13 |
| February | 4.18 |
| March | 3.75 |
| April | 2.59 |
| May | 1.78 |
| June | 1.49 |
| July | 0.79 |
| August | 1.02 |
| September | 1.63 |
| October | 3.19 |
| November | 5.9 |
| December | 5.62 |

e) The ARC for three lines from January (1) are
(1,5.13) & (4,3.75) = - 0.46
(1,5.13) & (7, 0.79) = - 0.72
(1, 5.13) & (11, 5.9) = .077
The ARC becomes an increasingly lower (negative number) as the hot summer months approach, before sky rocketing just above 0 into the cold and wetter winter months.
This means that there is more rain in the months that are closer to January and less in those further away (assuming continuous loop).
f)
g) (1,5.13) & (4, 4.33) = -.0266
This shows that the IRC at the month of January is -0.266 showing a coming decrease in the amount of rainfall that Seattle will be recieving.
h) The experiment analyses the rate of change in rainfall that the city experiences throughout the year. I know that this is the IRC because it is what we learned about in class during the last week. The point (4, 4.33) was a totally random guess so this is probably pretty far off, but we have yet to learn a more effective method in class.
Your graphs are great! I like that you included the bit about it being a continuous loops. I think that your explanations and graphs are also really good.
ReplyDeletebaxter,
ReplyDeletenice job! are you from seattle? i like the area but the topic of your post is why i could never live there. too much rain!
your graphs and calculations look good, as well as your tables. since, talking about the derivative or the IRC means we are talking about rates, don't forget to include the units in your calculations and in your discussion of your results.
other than that, good job!
