Given the code below, what will be the output for the count and min values?
import numpy as np
from scipy.stats import describe
arr = np.array([4, 8, 15, 16, 23, 42])
stats = describe(arr)
print(stats.nobs, stats.minmax[0])
A6 42
B6 4
C5 4
D6 15
Step-by-Step Solution
Solution:
  1. Step 1: Understand the input array and function output

    The array has 6 elements: 4, 8, 15, 16, 23, 42. The describe function returns an object with nobs as count and minmax as (min, max) tuple.
  2. Step 2: Extract count and minimum

    stats.nobs is 6 (number of elements), stats.minmax[0] is 4 (minimum value).
  3. Final Answer:

    6 4 -> Option B
  4. Quick Check:

    Count = 6, Min = 4 [OK]
Quick Trick: nobs = count, minmax[0] = minimum value [OK]
Common Mistakes:
MISTAKES
  • Confusing minmax[0] with max
  • Counting elements incorrectly
  • Mixing up index positions
