Negative Z Score Table. If you get a negative z score, this shows that the raw score is lower than the mean average. Use the negative z score table below to find values on the left of the mean as can be seen in the graph alongside.

It means that the observed value is below the mean of total values.

This table format helps in deducing area or the probability ranging from the negative infinity (the last left) and then going right above the required. To map a z score across a z table, it goes without saying that the first thing you need is the z score itself. The z score itself is a statistical measurement of the number of standard variations from the mean of a normal distribution. Table entries for z define the area under the standard normal curve to the left of the z. We would use this if our test score was below the population. A few examples should make this clear. Use the negative z score table below to find values on the left of the mean as can be seen in the graph alongside. F distribution for α = 0.10. Use of negative z score table. It's a great way to check your work.
