Q3: Lesson 3 | Normal Distribution (MA'AM IVY) Flashcards
is a distribution of a continuous random variable whose graph is a bell-shaped curve called normal curve
normal distribution
The graph of normal distribution is a bell-shaped curve is called____
normal curve
is symmetric about the mean and half of the area is above the mean while the remaining half is below the mean.
normal curve
is asymptotic to the horizontal axis.
normal curve
is determined by two parameters, the mean and standard deviation
normal distribution
measures how many standard deviation a given value (x) is above or below the mean. The z-scores are useful for comparing observed valuess.
standard score or z-scores
They allow to find the probability of a score occurring within a normal distribution and enable us also to compare two scored that are from different normal distribution.
standard scores or z-scores
indicates that the score or observed value is above the mean,
positive z-scores
indicates that the score or observed value is below the mean.
negative z-score
