Understanding Statistical Measures

Here is a brief explanation of each statistical measure available in our calculator:

Mean

The mean (average) of a dataset is calculated by summing all the values and dividing by the number of values. The formula is:

\[ \text{Mean} = \frac{\sum_{i=1}^{n} x_i}{n} \]

For example, the mean of the dataset \([1, 2, 3, 4, 5]\) is:

\[ \text{Mean} = \frac{1 + 2 + 3 + 4 + 5}{5} = 3 \]

Median

The median is the middle value of a dataset when the values are arranged in ascending order. If there is an even number of values, the median is the average of the two middle values.

For example, the median of the dataset \([1, 2, 3, 4, 5]\) is:

\[ \text{Median} = 3 \]

For the dataset \([1, 2, 3, 4]\), the median is:

\[ \text{Median} = \frac{2 + 3}{2} = 2.5 \]

Mode

The mode is the value that appears most frequently in a dataset. A dataset can have one mode, more than one mode, or no mode at all.

For example, the mode of the dataset \([1, 2, 2, 3, 4]\) is:

\[ \text{Mode} = 2 \]

The dataset \([1, 2, 3, 4, 5]\) has no mode because all values appear only once.

Standard Deviation

The standard deviation measures the amount of variation or dispersion in a dataset. The formula is:

\[ \sigma = \sqrt{\frac{\sum_{i=1}^{n} (x_i – \mu)^2}{n}} \] where \(\mu\) is the mean of the dataset.

Variance

The variance measures the spread of a dataset. The formula is:

\[ \sigma^2 = \frac{\sum_{i=1}^{n} (x_i – \mu)^2}{n} \] where \(\mu\) is the mean of the dataset.
