Front

What is the treatment in an experiment?

Back

The treatment refers to the specific condition or intervention applied to the experimental units in an experiment.

Front

Define the response variable in an experiment.

Back

The response variable is the outcome that is measured to assess the effect of the treatment.

Front

What is an experimental unit?

Back

An experimental unit is the smallest division of the experimental material such that any two units may receive different treatments.

Front

What does the five-number summary include?

Back

The five-number summary includes the minimum, first quartile (Q1), median, third quartile (Q3), and maximum.

Front

How do you calculate the maximum length of the right-side whisker in a boxplot?

Back

The maximum length of the right-side whisker is calculated as Q3 + 1.5 * IQR, where IQR is the interquartile range.

Front

What is the interquartile range (IQR)?

Back

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1), representing the middle 50% of the data.

Front

When is the median a better measure of center than the mean?

Back

The median is a better measure of center when the data distribution is skewed or contains outliers.

Front

What does it mean if the mean is less than the median?

Back

If the mean is less than the median, it indicates that the distribution is negatively skewed.

Front

How do you find the probability of an event?

Back

The probability of an event is found by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is a boxplot used for?

Back

A boxplot is used to visually display the distribution of a dataset, highlighting the median, quartiles, and potential outliers.
