Neither. They are measures of different things Kilos or kilograms are measures of mass. Miles are measures of linear distance.
Each of these measures of central tendency has its own advantages and disadvantages. Different measures are best in different circumstances.
Used when you have an experiment with several related dependent measures. Also used to analyze data from a within subject design.
The data collected in an experiment measures the variables identified in the research question or hypothesis. These measurements help to quantify the relationships between different factors and provide evidence to support or reject the hypothesis.
Yes, a controlled experiment is designed to measure the effect of one specific variable while holding all other variables constant. This allows researchers to determine the direct impact of the variable of interest on the outcome being studied.

Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.
When performing an experiment you want to be sure you are following precaution. You should wear safety goggles, protective clothing and gloves.
The smart pulley used in this experiment measures the force applied to the pulley, as well as the resulting acceleration and velocity of the object attached to it. It can provide real-time data on these parameters, allowing for a detailed analysis of the motion of the object.
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.

To measure relative humidity, you would need a hygrometer, which can be a mechanical or electronic device. In addition, you may need a source of temperature data as relative humidity is temperature-dependent. Optionally, you might use a psychrometer, which consists of two thermometers – a dry-bulb and a wet-bulb – to calculate relative humidity based on the temperature difference.

He most likely Mike will have to measure or compare the masses of some objects. MIKE HAS HUGE OBJECTS THAT HE MEASURES EVERY NIGHT . HE HAS MEASUREMENTS IN YOUR MOMMYS MOUTH AND HE PUTS IT IN TO SEE HOW DEEP IT WILL GO..THATS HOW MIKE MEASURES HIS OBJECTS
different places may have different measures.
