What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is a measure of statistical dispersion, calculated as the difference between the third quartile (Q3) and the first quartile (Q1). It represents the range of the middle 50% of the data.

Front

How do you identify outliers using the IQR?

Back

Outliers can be identified using the IQR by calculating the lower bound (Q1 - 1.5 * IQR) and the upper bound (Q3 + 1.5 * IQR). Any data points outside these bounds are considered outliers.

Front

What does it mean if a data set is negatively skewed?

Back

A negatively skewed data set has a longer tail on the left side of the distribution, indicating that the majority of the data points are concentrated on the right.

Front

What is the definition of a percentile?

Back

A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls.

Front

What is the mean in a data set?

Back

The mean is the average of a set of numbers, calculated by dividing the sum of all values by the number of values.

Front

What is standard deviation?

Back

Standard deviation is a measure of the amount of variation or dispersion in a set of values. A low standard deviation indicates that the values tend to be close to the mean, while a high standard deviation indicates that the values are spread out over a wider range.

Front

How do you calculate the probability of getting a specific number of heads when flipping a coin multiple times?

Back

The probability can be calculated using the binomial probability formula: P(X = k) = (n choose k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, and p is the probability of success on an individual trial.

Front

What is a normal distribution?

Back

A normal distribution is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Front

What does it mean for a distribution to be approximately normal?

Back

A distribution is approximately normal if it follows the shape of a normal distribution closely enough that statistical methods based on normality can be applied.

Front

What is the relationship between mean, median, and mode in a normal distribution?

Back

In a normal distribution, the mean, median, and mode are all equal and located at the center of the distribution.
