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.

What is the middle score of a data called as?
The middle score of a data set is called the median. It is the value that separates the higher half from the lower half of the data when it is arranged in ascending or descending order. If there is an even number of observations, the median is the average of the two middle numbers.
How do you find the lower quartile range on a dot plot?
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.
What is the median of the lower half of a set of data. this is one of the 5 pieces plotted in a box-and-whisker plot.?
It is the lower quartile.
How do you find upper and lower quartiles In math?
To find the upper and lower quartiles of a data set, first, arrange the data in ascending order. The lower quartile (Q1) is the median of the lower half of the data, while the upper quartile (Q3) is the median of the upper half. If the number of data points is odd, exclude the median when determining these halves. Finally, use the following formulas: Q1 is the value at the 25th percentile, and Q3 is at the 75th percentile of the ordered data set.
What divides a set of data in half?
Median

What does the median tell you about the data?
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.
What does the median of a set of data tell you?
The median is the midpoint of the data set. So half the observations are greater than the median and half are smaller.
What divides a set of data in half?
Median
What is the example of the lower quartile?
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
How do you solve a third quartile?
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.
What is the median of the lower half of a set of numbers?
The lower quartile.
What is meant by the median of a set of data?
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.
