1Which of the following best describes the sample standard deviation in statistical data analysis?
A.A measure of the central value of a dataset
B.A measure of how spread out data values are around the sample mean
C.The difference between the maximum and minimum values in a sample
D.The proportion of sample values that lie within one standard error of the median
Explanation: Sample standard deviation measures the average distance or dispersion of individual data points from the sample mean. It provides insight into the variability of a dataset.
2In a standard normal distribution N(0, 1), what does a z-score of +1.5 indicate?
A.The observation is 1.5 units above the median
B.The observation is 1.5 standard deviations above the population mean
C.The observation is 1.5 times greater than the sample variance
D.The observation lies in the bottom 15% of the distribution
Explanation: A z-score standardizes a raw value by subtracting the mean and dividing by the standard deviation. A value of z = +1.5 means the data point is exactly 1.5 standard deviations above the mean.
3If events A and B are mutually exclusive, which of the following equations correctly states the probability of event A or event B occurring?
A.P(A or B) = P(A) + P(B)
B.P(A or B) = P(A) x P(B)
C.P(A or B) = P(A) + P(B) - P(A and B)
D.P(A or B) = P(A) / P(B)
Explanation: When two events are mutually exclusive, they cannot occur simultaneously, meaning P(A and B) = 0. Therefore, the addition rule simplifies to P(A or B) = P(A) + P(B).
4Using standard normal tables, what is the approximate probability that a standard normal variable Z is less than 1.00 (i.e. P(Z < 1.00))?
A.0.5000
B.0.6827
C.0.8413
D.0.9500
Explanation: The standard normal distribution is symmetric about 0 with 50% below 0. The area between 0 and 1 standard deviation is approximately 0.3413. Thus P(Z < 1.00) = 0.5000 + 0.3413 = 0.8413.
5What is the primary difference between a sample statistic and a population parameter?
A.A statistic describes a characteristic of a sample, while a parameter describes a characteristic of an entire population
B.A parameter changes with every sample collected, while a statistic remains constant
C.A statistic is represented by Greek letters like mu and sigma, while a parameter uses Latin letters like x-bar and s
D.Parameters are calculated from surveys, while statistics are derived only from complete censuses
Explanation: A statistic is a numerical measure calculated from sample data (e.g. x-bar or s), whereas a parameter is a fixed numerical value describing an entire population (e.g. mu or sigma).
6A research study finds that the Pearson correlation coefficient between study hours and exam performance is r = 0.85. How should this result be interpreted?
A.Strong negative linear relationship
B.Weak positive linear relationship
C.Strong positive linear relationship
D.No linear relationship
Explanation: Pearson's correlation coefficient r ranges from -1 to +1. A value of r = +0.85 is close to +1, indicating a strong positive linear relationship between the two variables.
7Which mathematical formula represents the standard error of the sample mean (SE) for a sample size n with sample standard deviation s?
A.SE = s / n
B.SE = s / sqrt(n)
C.SE = s^2 / n
D.SE = sqrt(s) / n
Explanation: The standard error of the mean estimates the standard deviation of the sampling distribution of sample means. It is calculated by dividing the sample standard deviation s by the square root of the sample size n: SE = s / sqrt(n).
8A fair coin is tossed twice. What is the probability of obtaining two heads in succession?
A.0.25
B.0.50
C.0.75
D.1.00
Explanation: Because each coin toss is independent, P(Head and Head) = P(Head) x P(Head) = 0.5 x 0.5 = 0.25 (or 1/4).
9In medical and epidemiological statistics, how is Relative Risk (RR) defined when comparing an exposed group to an unexposed group?
A.Risk in exposed group minus Risk in unexposed group
B.Risk in exposed group divided by Risk in unexposed group
C.Odds of exposure in cases divided by Odds of exposure in controls
D.Risk in unexposed group divided by Risk in exposed group
Explanation: Relative Risk (RR) measures the ratio of the probability of an outcome occurring in an exposed group to the probability of the outcome occurring in a non-exposed group: RR = Risk(Exposed) / Risk(Unexposed).
10In a 2x2 contingency table, if the odds of disease among exposed individuals is 4 to 1 and among unexposed individuals is 1 to 1, what is the Odds Ratio (OR)?
A.2.0
B.3.0
C.4.0
D.5.0
Explanation: The Odds Ratio is calculated by dividing the odds of disease in the exposed group (4/1 = 4) by the odds of disease in the unexposed group (1/1 = 1). OR = 4 / 1 = 4.0.
