Assignment 1: Questions
January 22, 2008
1. A random event is one in which the determining factors are so many that they cannot be determined, and therefore the event cannot be predicted. For example, the rolling of dice, or the drawing of a playing card are random events. On the other hand, a systematic event is one in which there is some sort of bias, which makes the event more predictable.
2. It is never possible to exactly predict the next temperature value, or in fact correctly predict any future event. Each time that the temperature is taken, it is a random event. There are many factors that play into what a person’s body temperature will be, and therefore it would be impossible to correctly guess the temperature, just as it would be impossible to guess the IQ of the next baby born.
3. Systematic events present in our data were difficult to find, but when looking closely at the data, one can see that temperatures are lower in the morning and evening, and seem to peak in the afternoon. Temperatures were higher after periods of exercise, and lower after periods of being in cold weather.
4. 7 sources of random variation that affect my life are…
1–Mood, which is affected by many different things, but has a major impact on my day
2–The availability of parking spots, which is also affected by many different things, but can also impact my day
3–Wellness, again, affected by many different things, but being sick would definitely impact a day
4–Weather, cannot be predicted but affects what clothing is worn, what activities can be done
5–Traffic, is a random event but can change how one’s day turns out
6–Interactions with people, vary very much from day to day, but can affect how one feels throughout the day
7–The moods of other people, are random and will affect your mood
5. Sources used:
–WebMD Article on Body Temperature
–Class Lectures

I only see one graph, is there another? I only see 6 examples of randomless, there should be at least 7. Any references or sources about the topic of randomness?
