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.
How do you get the lower class boundary of the median?
The median is the middle number in a data set. The lower class boundary is the first quartile or number that is 25 percent lowest in the data set.
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
What does a box and whisker chart show?

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 are the 5 values for a box plot?
They are 1: the minimum 2: the lower quartile 3: the median 4: the upper quartile 5: the maximum. Sometimes the extrema (minimum and maximum) are plotted AFTER excluding outliers.
What is the median of the lower half of a set of numbers?
The lower quartile.
What is the median of the lower half of a data set called?
It is the lower quartile.
How do you find the lower and upper quartile?
U find the upper quartile by going to ur data and finding the median by ur median and the lower or upper extreme
Can the average be lower than the median?
Yes. Higher or lower. The average is the sum of the elements divided by the number of elements. The median is the average of only the highest and lowest numbers.. For the numbers 0,5,100, the median is 50 and the average is 35. For the numbers 0,53,100 the median is still 50 and the average is 51.
Why is the mean lower than the median?
because mean you add all the number and median you look for the number in the middel
How do you get the lower class boundary of the median?
The median is the middle number in a data set. The lower class boundary is the first quartile or number that is 25 percent lowest in the data set.
What is a define median?
The median is defined as the middle value in a set or distribution. There is no arithmetic involved in finding the median unless the set or distribution has an even number of values, in which case the the two middle values (sometimes defined as lower median and upper median) are averaged to find the median.
Can the mean be smaller than the median for a set of data?
Yes. If the lower values tend to be farther below the median than the highest values are above the median, the mean is smaller than the median. why are write wrong

Can the median ever be higher than the average?
Yes. It can be higher or lower
