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 is the median of the lower half of a set of numbers?
The lower quartile.
What is the median of the upper half of the data set?
It is the upper quartile.
What is a lower 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.
What is the median in a set of data?
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)
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.
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 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.
What is the median of the lower half of a set of numbers?
The lower quartile.
The middle number in a set of data showing that half of the data falls and half comes after it?
median
What information is viewed on a box and whisker plot?
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.
What is the median of the upper half of the data set?
It is the upper quartile.
How do you find the inner and outer quartiles?
To find the inner quartiles (Q1 and Q3), first arrange your data in ascending order. Q1 is the median of the lower half of the data, and Q3 is the median of the upper half. The inner quartiles divide the data into four equal parts. The outer quartiles also known as the minimum and maximum values, are the smallest and largest values in the data set.
