The range mean, often referred to as the midrange, is calculated using only the maximum and minimum values in a dataset, not all observations. It is computed by averaging these two values, which means it does not take into account the distribution or frequency of the other data points. Therefore, while it provides a measure of central tendency, it does not reflect the overall characteristics of the entire dataset.
Inferences should be based on objective observation and logical reasoning.
Science is based on a mixture of all three: observations, laws of nature, and experimental data. The root of science, however, lies in observation.
what is all your nameshow did you all make this?i need you all to come to my b-day 1d and sing save you tonight in winnipeg all right?i am tring 10 on septmber 24 monday okey!!
observation
While involved in focused observation many senses are employed. The sense of sight, hearing, touch, taste and smell can all play an important part in a detailed observation.
The science method is all based on the observation experimentation. It is to do different studies.
Inferences should be based on objective observation and logical reasoning.
You treat each observation in a particular range as if it were the middle value of that range.
Advantage:1- it based on observed values just like Arithmetic Mean and Harmonic Mean. 2- it gives equal weightage to all observations.Disadvantage:1- It vanishes if any observation is zero.2- In case of -vevalues it cannot be computed at all.

Mean or more precisely Arithmetic Mean
Observation is the act of watching something.
You need to have all the values within the range to calculate the arithmetic mean .
all the data added together
Range is defined as all possible y values in a relation.
There is no actual "smallest" observation - a standard deviation of zero means that all 100 of the observations had to be 46.
take the values from the chart and then add all the observations by total number of observation! it is good that it is not a polygon!
