Answer #1

1. Grubbs test is a statistical method used to identify outliers in a dataset that is a part of normally distributed population.

G= |questionable data- mean| / std deviation

2. Confidence interval in statistics is a type of interval estimation in which there is maximum probability to find the true data of a parameter.

3. Standard deviation is a quantity that expresses how much the members of a group varies from the mean of the group.

4. Absolute uncertainty is the size of range of values in which the true value of the measurement probably lies.
