The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.

The lower quartile.

It is the upper quartile.

A lower quartile i s the mediaon of the lower half of a data set. A data set is divided up into different quartiles.

The middle value so half the data is above it and half the data is below it. It is often used because extreme values tend to affect it less than other measures of central tendency. If you have an even number of data points, the median is the mean of those two points. ( So you add the two values and divided by two)

It is the lower quartile.

The median, by definition, tells you the "half way point" of your data. Exactly half of the observations in the dataset will be less than the median and half will be greater than the median.

The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.

Lower Quartile (Q1): the number that divides the lower half of the data into two equal halves. For example, given this data: 25, 26, 27, 28, 29, 30, 40, 41, 42 The Median is 29. Now, you need to find the lower quartile. You want to look at all the data that is below the median, so: 25, 26, 27, 28, The median splits the data into two groups. Find the median of the lower group, which is 26.5 ((26+27)/2). The lower quartile is 26.5

Roughly speaking, finding the third quartile is similar to finding the median. First, use the median to split the data set into two equal halves. Then the third quartile is the median of the upper half. Similarly, the first quartile is the median of the lower half.

The lower quartile.

In probability theory and statistics, a median is described as the number separating the higher half of a sample from the lower half.So if you have 19 measurements and order them from least to greatest, the tenth value is the median.

median

It is an overview of the distribution of a data set. The values that are plotted are:the minimum,the lower quartile (a quarter of the data points are smaller),the median (half the data points are smaller),the upper quartile (a quarter of the data points are larger),the maximum.

It is the upper quartile.

The median is a measure of central tendency. In a set of data, it is the value such that half the observed values are larger and half are smaller.
