Let's calculate the mean, median, mode, sample variance, and sample standard deviation for the given data set: {2, 3, 6, 6, 2, 7, 2}.\r
\n" ); document.write( "\n" ); document.write( "**1. Mean:**\r
\n" ); document.write( "\n" ); document.write( "* Sum of the values: 2 + 3 + 6 + 6 + 2 + 7 + 2 = 28
\n" ); document.write( "* Number of values: 7
\n" ); document.write( "* Mean: 28 / 7 = 4\r
\n" ); document.write( "\n" ); document.write( "**2. Median:**\r
\n" ); document.write( "\n" ); document.write( "* First, arrange the data in ascending order: 2, 2, 2, 3, 6, 6, 7
\n" ); document.write( "* The median is the middle value. Since there are 7 values, the median is the 4th value.
\n" ); document.write( "* Median: 3\r
\n" ); document.write( "\n" ); document.write( "**3. Mode:**\r
\n" ); document.write( "\n" ); document.write( "* The mode is the value that appears most frequently.
\n" ); document.write( "* In this data set, 2 appears 3 times, which is more than any other value.
\n" ); document.write( "* Mode: 2\r
\n" ); document.write( "\n" ); document.write( "**4. Sample Variance (s²):**\r
\n" ); document.write( "\n" ); document.write( "* Calculate the squared differences from the mean:
\n" ); document.write( " * (2 - 4)² = 4
\n" ); document.write( " * (3 - 4)² = 1
\n" ); document.write( " * (6 - 4)² = 4
\n" ); document.write( " * (6 - 4)² = 4
\n" ); document.write( " * (2 - 4)² = 4
\n" ); document.write( " * (7 - 4)² = 9
\n" ); document.write( " * (2 - 4)² = 4
\n" ); document.write( "* Sum of squared differences: 4 + 1 + 4 + 4 + 4 + 9 + 4 = 30
\n" ); document.write( "* Divide by (n - 1), where n is the number of values (7 - 1 = 6):
\n" ); document.write( "* Sample variance: 30 / 6 = 5\r
\n" ); document.write( "\n" ); document.write( "**5. Sample Standard Deviation (s):**\r
\n" ); document.write( "\n" ); document.write( "* The sample standard deviation is the square root of the sample variance.
\n" ); document.write( "* Sample standard deviation: √5 ≈ 2.236\r
\n" ); document.write( "\n" ); document.write( "**Summary:**\r
\n" ); document.write( "\n" ); document.write( "* Mean = 4
\n" ); document.write( "* Median = 3
\n" ); document.write( "* Mode = 2
\n" ); document.write( "* Sample Variance = 5
\n" ); document.write( "* Sample Standard Deviation ≈ 2.236
\n" ); document.write( "
\n" ); document.write( "
\n" );
