Statistical analysis Flashcard

A Box and Whisker Plot is a graphical representation of a data set that shows its minimum, first quartile, median, third quartile, and maximum.

The Maximum value is the largest number in a data set.

The First Quartile (Q1) is the median of the lower half of a data set, representing the 25th percentile.

To find the Median, arrange the data in order and locate the middle value. If there is an even number of values, average the two middle values.

The Median is the middle value of a data set when arranged in ascending order.

A statistical question is one that anticipates variability in the data and can be answered by collecting data.

No, it is not a statistical question because it has only one possible answer.

The Mean is the average of all data values, while the Median is the middle value when the data is ordered.

A Quartile is a type of quantile that divides a data set into four equal parts.

The purpose of a Box and Whisker Plot is to visually summarize the distribution of a data set and identify outliers.
