Normal Distribution — Flashcards

Flashcard 1: The horizontal line on either side of rectangles in the Forest plot represent _____

Answer: confidence intervals

Flashcard 2: What type of distribution is characterized by a long tail on the left side and Mean < Median < Mode?

Answer: Negatively skewed (Left-skewed)

Extra: In a negatively skewed distribution, the tail is on the left side (lower values). The relationship between measures of central tendency is: Mean < Median < Mode.

Flashcard 3: The confidence interval is smaller with a _____ sample size.

Answer: larger (larger/smaller)

Flashcard 4: What type of distribution is characterized by a tail extending towards the right side, where the Mean > Median > Mode?

Answer: Positively skewed (Right-skewed) distribution

Extra: In a positively skewed distribution: - Tail extends towards the right (positive side). - Mean > Median > Mode. Conversely, in a negatively skewed (left-skewed) distribution: - Tail extends towards the left (negative side). - Mean < Median < Mode.

Flashcard 5: In a distribution with outliers, preferred measure of central tendency is the _____.

Answer: median

Flashcard 6: What type of distribution is characterized by a symmetrical bell-shaped curve where the mean, median, and mode coincide?

Answer: Normal distribution (Gaussian distribution)

Flashcard 7: What type of distribution is this? _____

Answer: Normal

Flashcard 8: What type of distribution is this? _____

Answer: Negative/Left

Flashcard 9: What type of distribution is this? _____

Answer: Positive/Right

Flashcard 10: What type of bar graph is represented below? _____
