Solve: x2 - 5x + 2 = 0
Solve: x2 - 5x + 2 = 0
x = 5/2 +/- sqrt(17)/2
a) Explain what IQR is and how it's calculated.
b) Explain what outliers are and how they're calculated.
a) Explain what IQR is and how it's calculated.
Range of middle 50% of data. IQR = Q3 - Q1
b) Explain what outliers are and how they're calculated.
Extreme high or low values. Outlier:
x < Q1 - 1.5(IQR) or x > Q3 + 1.5(IQR)
Consider a boxplot where the distance between the minimum and Q1 is greater than the distance between Q3 and the maximum. The distance between Q1 and the median is about the same as the distance between the median and Q3. Which of the following is true about this data?
a) mean = median
b) mean < median
c) mean > median
d) relationship between mean and median cannot be determined
