When locating the column in a z-score table, you need to consider the second digit of your z-score. The columns represent the second digit(s) of your z-score.
For example, if your z-score is 1.36, you would locate the row that starts with “1.3” and then move horizontally to find the column that corresponds to the second digit “6”. The value at the intersection of this row and column will give you the proportion or probability associated with that particular z-score.
In summary, when using a z-score table, you locate the row based on the first digit(s) of your z-score and then move horizontally to find the column based on the second digit(s) of your z-score.
