Tevy Nuon and Megan Cross... I Get a Shiver in My Bones

Regression Project
D). Scatter Plot for the average weather in: Syracuse, New York, Jefferson City, Missouri, Barcelona, Spain

SYRACUSE:

Equation: Sine Regression y= (a)(sin(bx+c)) +d
y=(12.78984)(sin(.5643x- 2.66123) + 60.4501
amplitude: 12.78984
wrap line: 60.4501
x= the month
y= the approximate temperature






JEFFERSON CITY, MISSOURI
Equation: Sine Regression y=(a)(sin(bx+c))+d
y= (25.2057)(sin(.48599x - 1. 87728) +51.69428
amplitude: 25.2057
wrap line: 51.69428
x= the month
y= the approximate temperature








BARCELONA, SPAIN
Equation: Sine Regression y= (a)(sin(bx+c))+d
y= (12.798)(sin(.56433x - 2.66124)) + 60.45
amplitude: 12.798
wrap line: 60.45
x=the month
y= the approximate temperature







  • The wrap line represents the point in the graph where the y-intercept starts. It is also the line that cuts the graph in half horizontally. If the wrap line is greater than zero the whole graph shifts upwards based in the number given. If the wrap line is less than zero the whole graph shifts downwards based on the number given.

  • The amplitude represents how high the graph goes representing the maximum and minimum points. In the situation it represents the highest and lowest average temperatures.

  • The three locations seem to have similar temperature in each month. The highest value of Syracuse is in August at 70. For Jefferson City, Missouri, it is 77.4 in July. In addition, for Barcelona, Spain, it is 74. So Syracuse and Barcelona have their highest temperatures in August while Jefferson City has it is highest in July. Therefore, they all have their highest temperatures in the summer time. Syracuse’s lowest temperature is 24 in January. Jefferson City is 27.4 in January, and for Barcelona, its lowest temperature is 48 in January. They all have their lowest temperatures in January, though Spain’s is a lot more than Syracuse and Jefferson City’s temperatures. Another different thing is that Spain’s averages are higher than the others for winter, while Syracuse has the lowest. But for summer, Jefferson City has the highest averages. In addition, for spring, Barcelona has the highest averages while Syracuse has the lowest. Some of Barcelona’s averages are equal to Syracuse ‘s averages by a month later. For example, Syracuse is 70 in August when Barcelona is 70 in September, and it goes for September to October.

  • My favorite temperature is early to mid 70’s. Warm, sunny, and breezy. Warm enough to wear shorts and sandals but cool enough to wear jeans, or denim jackets. I do not think 70 is hot I think its more mild to me. According to the data and graph, the best time to go Jefferson Missouri and Barcelona Spain would be from July to September. For Jefferson City, it would be from June to September.
