Nature of Data
What is a parameter?
A graph depicting qualitative data as slices of pie.
What is a pie chart?
The maximum value - the minimum value.
What is the range?
The probability of drawing a black card from a standard deck of 52 cards.
What is 1/2?
A description that gives the probability for each value of the random variable. It is often expressed in the format of a graph, table, or formula.
What is probability distribution?
Chapter 2: Summarizing and Graphing Data
What is my favorite chapter from this semester?
Math is cool.
What is the truth?
The type of result when the number of possible values is either a finite number or is countable.
What is discrete?
A graph in which each data value is plotted as a point along a scale of values, where equal values are stacked.
What is a dot plot?
The measure of variation of all values from the mean.
What is standard deviation?
The notation of the probability of event B occurring after event A has already occurred.
What is P(B|A)?
The two requirements for a probability distribution.
What is 1. ∑P(x) = 1
and 2. 0 ≤ P(x) ≤ 1?
Chapter 4: Probability
What is my least favorite chapter from this semester?
Matt is as old as a dinosaur.
What is something everyone knows?
The four types of continuous data.
What is nominal, ordinal, interval, and ratio?
The type of data required for constructing a time-series graph.
What is data collected at different points in time?
The equation used to estimate the maximum "usual" sample value.
What is x̅ + 2s?
The probability of drawing a multiple of 3 (from a standard deck of cards) and rolling a 3 (from a standard die).
What is 1/26?
The formula for finding the mean for a probability distribution.
μ = ∑[x ⋅ P(x)]
Finding ways to manage my time and effectively use my resources.
What is something that an independent learning class has taught me?
Not likely.
What is the probability of Charlie taking discrete math next semester?
The level of measurement that includes meaningful differences and the natural zero starting point.
What is ratio level?
A line graph that depicts cumulative frequencies, just as the cumulative frequency distribution lists them.
What is an ogive?
? = √ ∑(x - x̅)2 / n - 1
What is sample standard deviation?
The probability of drawing a 5 and then a 7 (from a standard deck of cards) with replacement.
What is 1/169?
The formula for finding the standard deviation for a probability distribution.
σ = √ ∑[x2 ⋅ P(x)] - μ2
Learning statistics taught me how to better organize, graph, and analyze data. Along with that, I can use the skills I learned in this class for my senior research project.
What is a way this statistics class might help me in the future?
Statistics!
What is a class everyone should take?
The level of measurement used to describe letter grades (A-F).
What is ordinal?
The main objective in graphing data.
DAILY DOUBLE!! What is visualizing variation and showing the relationship between values?
The properties of the Empirical Rule for data with a bell-shaped distribution.
What is about 68% of all values falling within 1 standard deviation of the mean, about 95% of all values falling within 2 standard deviations of the mean, and about 99.7% of all values falling within 3 standard deviations of the mean?
The probability of rolling a standard die twice and getting a sum less than 12.
What is 35/36?
The rule that claims if under a given assumption (like a coin is fair), the probability of a particular observed event is extremely small, we conclude that the assumption is probably not correct.
What is the Rare Event Rule?
I improved on fundamental test taking skills as well as taking more detailed notes than I have in the past.
What is my biggest improvement as a math student this semester?
The outcome that is more likely to happen: A) Rolling a pair of dice and getting a sum of 10 OR B) Drawing two cards from a standard deck of 52 and getting a "pair".
What is Choice A?
