**Measuring "The Spread" Range Interquartile Range**

13/12/2013Â Â· The difference between the upper (3rd) quartile and the lower (1st) quartile gives us the InterQuartile Range (IQR), another measure of spread. The IQR also gives us a way to determine if we have outliers in the data, as each of the first and last quarters of the data can not spread any further than 1.5 x IQR, so any values that do lie outside this spread are considered outliers....17/10/2012Â Â· A quick and easy how-to guide for finding measures of central tendency relating to statistics such as the mean, median, mode, range, standard deviation, first quartile, third quartile, sum, max

## How To Find Lower Quartile With Mean And Standard Deviation

### 1) The Quartile deviation is 0.6745 times the standard deviation 2)The Quartiles (first and third or lower and upper) are equidistant from the median 3) The Mean, Median and â€¦

- Like the standard deviation, the interquartile range (IQR) is a descriptive statistic used to summarize the extent of the spread of your data. The IQR is the distance between â€¦ the 1st quartile (25th percentile) and 3rd quartile (75th percentile). Q3 - Q1 = IQR To find these numbers you must divide your data set in half, and find the median of each half and that will be your Q1 and Q3. If

- It depends on the lower quartile ${Q_1}$ and the upper quartile ${Q_3}$. The difference ${Q_3 - Q_1}$ is called the inter quartile range. The difference ${Q_3 - Q_1}$ divided by 2 is called semi-inter quartile range or the quartile deviation.
- Instead, to find the sample standard deviation and sample variance of the dataset of exam scores, you can use the Variance and Standard Deviation calculator, which tells you that the sample variation is 113.43 and the sample standard deviation is 10.65.
