To solve the problem, we need to follow these steps:

### Step 1: Determine the Number of Degrees of Freedom
The number of degrees of freedom (df) for a sample is typically calculated as:
$$
df = n - 1
$$
where $$ n $$ is the sample size.

### Step 2: Find the Critical Value $$ t_{\alpha / 2} $$
For a $$ 95\% $$ confidence level, we need to find $$ t_{\alpha / 2} $$ where $$ \alpha = 1 - 0.95 = 0.05 $$. Since this is a two-tailed test, we will look for $$ t_{0.025} $$ in the t-distribution table.

### Step 3: General Description of Degrees of Freedom
The correct description of degrees of freedom is that it represents the number of values in the final calculation of a statistic that are free to vary.

Now, let's proceed with the calculations. Please provide the sample size $$ n $$ so that we can calculate the degrees of freedom and find the critical value $$ t_{\alpha / 2} $$.
To find the critical value $$ t_{\alpha / 2} $$ for a $$ 95\% $$ confidence level, first determine the degrees of freedom (df) using $$ df = n - 1 $$. Then, look up $$ t_{0.025} $$ in the t-distribution table corresponding to the calculated df. The degrees of freedom represent the number of independent pieces of information that go into the estimate of a parameter.
