Understanding Statistical Measures in Birth Data

These flashcards cover key statistical concepts from the lecture on birth weights and labor duration.

Mean

The arithmetic average of a set of values, calculated by dividing the total of the values by the number of values.

Median

The middle value in a data set when the numbers are arranged in order.

Mode

The value that occurs most frequently in a data set.

Outlier

A data point that differs significantly from other observations, which can affect statistical measures like mean and median.

Range

The difference between the highest and lowest values in a data set.

Symmetrical Distribution

A distribution where the left and right sides are mirror images of each other, often resulting in the mean, median, and mode being the same.

Skewed Distribution

A distribution that is not symmetrical, where one tail is longer or fatter than the other, affecting the relationship between mean, median, and mode.

Active Labor Duration

The period during which a woman is actively experiencing contractions in preparation for childbirth.

Primigravida

A woman who is pregnant for the first time.

Clinical Application

The practical use of data analysis in a healthcare setting, often for patient education or clinical planning.
