After Generation 0

  1. What is the correct name for this type of graph?
    • A. Scatterplot
    • B. Histogram
    • C. Regression Line
    • D. Time Series
Click to see the answer

Answer: B. Histogram

Explanation: A Histogram is a special type of bar chart that shows the frequency distribution of another variable.
  1. What is your best estimate of the range of the data for Speed?
    • A. 1.0 to 5.5
    • B. 1.0 to 5.0
    • C. 0.0 to 12.0
    • D. 0.0 to 109.0
Click to see the answer

Answer: A. 1.0 to 5.5

Explanation: Values of Speed are shown on the x axis, and the range is defined as the lowest and highest value of the variable. The lowest value of Speed is in the 1.0 bin, and the highest value is in the 5.5 bin.
  1. What bin contains the Mode of the distribution for Speed?
    • A. 1.0 to 1.5
    • B. 109 Slimes
    • C. 2.0 to 2.5
    • D. 6.0 to 6.5
Click to see the answer

Answer: C. 2.0 to 2.5

Explanation: The Mode of a distribution is its most frequently observed value. In this case, the 2.0 to 2.5 bin contains the most slimes. 
Number of observations with Wave Number 0: 300
Correlation between Speed Trait and Tower Attraction Trait:
                        Speed Trait  Tower Attraction Trait
Speed Trait                1.000000                0.044419
Tower Attraction Trait     0.044419                1.000000
  1. What type of relationship appears to exist between Speed Trait and Tower Attraction Trait?
    • A. Strong positive correlation
    • B. Strong negative correlation
    • C. Weak positive correlation
    • D. No clear correlation
      Click to see the answer Answer: D. No clear correlation Explanation: The scatterplot shows no clear pattern or trend between Speed Trait and Tower Attraction Trait, indicating no clear correlation between these variables.
  2. What is the approximate range of values for the Tower Attraction Trait?
    • A. 0 to 6
    • B. 0 to 12
    • C. -6 to 6
    • D. -12 to 12
      Click to see the answer Answer: C. -6 to 6 Explanation: The y-axis of the scatterplot, which represents the Tower Attraction Trait, appears to range from approximately -6 to 6.
  3. On this graph, what does each individual point (circle) represent?
    • A. The maximum value of [Trait 1] and [Trait 2] from all previous Generations of slimes.
    • B. The average values of the Traits for each slime from Generation X.
    • C. The exact values of [Trait 1] and [Trait 2] for each slime from Generation X.
    • D. The probability that each Slime will reproduce this generation.
      Click to see the answer Answer: C. The exact values of [Trait 1] and [Trait 2] for each slime from Generation X. Explanation: This is a scatter plot of trait values from the previous generation. A scatterplot plots exact values for two quantitative variables (Traits) on two orthogonal axes.

After Generation 3

We should totally do a bargraph race at the end of the game! Plus other animated graphs!

  1. What is the correct name for this type of graph?
    • A. Scatterplot
    • B. Bar Chart
    • C. Regression Line
    • D. Time Series
Click to see the answer

Answer: B. Bar Chart

Explanation: A Bar Chart is used to represent a quantitative variable (the height of the bar) for a set of discrete groups (arranged on the x axis).
  1. What is your best estimate of the number of Blaster type slimes?
    • A. 11
    • B. 1
    • C. 0 to 300
    • D. 46
Click to see the answer

Answer: A. 11

Explanation: The number of slimes for each type is represented by the height of each bar. Try hovering over the Blaster type bar to see its corresponding value for the y axis.
  1. What type of slime is the least frequent in the population?
    • A. Blaster
    • B. Basic
    • C. Acid
    • D. Fire
Click to see the answer

Answer: D. Fire

Explanation: The least frequent slime type is the represented by the bar with the lowest value. In this case, there are only XXX fire slimes, a number lower than all the other groups.
  1. What type of relationship appears to exist between Fitness trait and number of Offspring?
    • A. Strong positive correlation
    • B. Strong negative correlation
    • C. Weak positive correlation
    • D. No clear correlation
      Click to see the answer Answer: A. Strong positive correlation Explanation: The scatterplot shows a strong positive correlation between Fitness and offspring.
  2. What is the approximate range of values for the number of offspring?
    • A. 0 to 6
    • B. 0 to 12
    • C. -6 to 6
    • D. -12 to 12
      Click to see the answer Answer: B. 0 to 12 Explanation: The y-axis of the scatterplot represents the number of offspring. The lowest point value is at zero and the highest is 12.
  3. On this graph, what does each individual point (circle) represent?
    • A. The maximum value of [Trait 1] and [Trait 2] from all previous Generations of slimes.
    • B. The average values of the Traits for each slime from Generation X.
    • C. The exact values of [Trait 1] and [Trait 2] for each slime from Generation X.
    • D. The probability that each Slime will reproduce this generation.
      Click to see the answer Answer: C. The exact values of [Trait 1] and [Trait 2] for each slime from Generation X. Explanation: This is a scatter plot of trait values from the previous generation. A scatterplot plots exact values for two quantitative variables (Traits) on two orthogonal axes.
