The Population of the data set. If there was a study of 5000 people, 50 were randomly selected as a sample, then "N" would be 5000.
In statistics, n is usually used to mean the number of observations or measurements which you have. So n = 7 means you have 7 observations or meadurements.

In statistics, the lower case "n" typically represents the sample size, which is the number of observations or data points collected in a study or experiment. It is crucial for calculating various statistical measures, such as means, variances, and confidence intervals. A larger sample size (larger n) generally increases the reliability of the results.
In statistics, "n-1" refers to the degrees of freedom used in the calculation of sample variance and sample standard deviation. When estimating variance from a sample rather than a whole population, we divide by n-1 (the sample size minus one) instead of n to account for the fact that we are using a sample to estimate a population parameter. This adjustment corrects for bias, making the sample variance an unbiased estimator of the population variance. It is known as Bessel's correction.
There are two types of statistics. One is called descriptive statistics and the other is inferential statistics. Descriptive statistics is when you use numbers. Inferential statistics is when you draw conclusions or make predictions.
n is the sample size.

n-1 means take the sample size and subtract 1 from it.
