Arrange the numbers in ascending order: 41,42,42,43,43,44,44,45,46,47

Count the number of terms: There are (10) terms

Because there is an even number of terms, identify the middle two terms: 41,42,42,43,43,44,44,45,46,47

Find the value that is halfway between the middle two terms by adding them together & dividing by 2: The median equals 43.5


To find the range, subtract the lowest value from the highest value. The highest value equals 47 The lowest value equals 41

The range equals 6


To find the sample variance, find the difference between each term và the mean, square the results, địa chỉ together all of the squared results, & divide the sum by the number of terms minus 1. The mean equals 43.7

To get the squared differences, subtract the mean from each term và square the result:


To get the sample variance, địa chỉ together the squared differences and divide their sum by the number of terms minus 1 Sum: Number of terms: Number of terms minus 1: 9 Variance:

The sample variance () equals 3.567

The standard deviation of the sample equals the square root of the sample variance. This is why the variance is usually represented by a squared variable. Variance:

Find the square root: The standard deviation () equals 1.889


The science of statistics đơn hàng with the collection, analysis, interpretation, & presentation of data, particularly in the contexts of uncertainty và variation. Understanding even the most basic of concepts in statistics can help us better process and understand information that we encounter in our everyday lives! Additionally, more data is collected now, in the 21st century, than ever before in all of human history. As computers have become more powerful, they have made it easier to analyze và interpret ever-larger datasets. Because of this, statistical analysis is becoming increasingly important in many fields, allowing governments và companies lớn fully understand & react to lớn data.
