temperature, change in barometric pressure, humidity
Noticing the sky is dark and hearing thunder in the distance are examples of observations.
Example of ground water are well, boreholes, river, lagoon and other ground surface water.
Just go outside and put your feet on the ground, that is an example of our lithosphere.
Geologists had to work together to develop the geologic column because it needed combined observations to create a standard arrangement of strata and time-spans.
temperature, change in barometric pressure, humidity

Scientific methods
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.

well i lost my shoes turns out to be my dog had it
Activity
It is a measure of the spread of the distribution. The greater the standard deviation the more variety there is in the observations.
The Army Standard for reporting observations is by utilizing the SALUTE Report format. What does the A stand for? It uses the passive voice.
by using your senses
If there is zero deviation all the observations are 50.
They are statistical measures. For a set of observations of some random variable the mean is a measure of central tendency: a kind of measure which tells you around what value the observations are. The standard deviation is a measure of the spread around the mean.
