The median of the lower half of a set of data is called the first quartile, often denoted as Q1. It represents the value below which 25% of the data lies and effectively divides the lowest 50% of the dataset into two equal parts. This measure is useful in understanding the distribution and spread of the lower portion of the data.
To find the lower quartile (Q1) on a dot plot, first, arrange the data points in ascending order. Then, identify the median of the lower half of the data, which includes all values below the overall median. Q1 is the median of this lower half, representing the 25th percentile. If there is an even number of values in the lower half, average the two middle values to determine Q1.
It is the lower quartile.
Median
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.
It is the lower quartile.
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.

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.

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.
Oh, dude, that's easy. So, like, the thing that divides the lower half of the data into two equal parts is the median. It's like the middle child of the data set, stuck between the rowdy younger half and the more mature upper half. Just think of it as the peacekeeper of the data family, keeping things balanced and fair.
