Why is range not a measure of central tendency?
Measures of central tendency are averages. Range , the difference between the maximum and the minimum, is a measure of dispersion or variation.
How do box plots describe data?
Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data. From the smallest to the largest, the statistics plotted are:The minimum valueThe lower quartile (the value of the variable that is greater than a quarter of the observations)The median (the value of the variable that is greater than half the observations)The upper quartile (the value of the variable that is greater than three quarters of the observations)The maximum value.(In slightly refined versions, outliers are separately identified).The median is a measure of central tendency (average value). The difference between the quartiles is a measure of dispersion or spread around the average. The relative values of the five indicate whether or not the data set is skewed.Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data.

What is the minimum population required for a bell curve?
There is no minimum number: very few observations can be indicative. As the population number increases the observations should get closer to the Normal distribution. You should have 30 or so observations to get a smooth-ish curve.
What does a box and whisker chart show?
It shows the minimum, lower quartile, median, upper quartile and maximum of a set of observations. It may show outliers separately.It shows the minimum, lower quartile, median, upper quartile and maximum of a set of observations.

What would the data set look like if you have only one whisker in the box plot?
If you do not have the left side whisker, it means that the minimum value and the lower quartile are the same. This means that the smallest 25% of the observations (or more) are all the same.If you do not have the left side whisker, it means that the minimum value and the lower quartile are the same.

What is the principle of maximum-minimum thermometers?
The advantage is the thermometer records a daily maximum and minimum temperature for reference. The disadvantage is the thermometer must be reset each day.
What is the disadvantage of retail market?
The main disadvantage of retail market is that they pay little more than the minimum wages. The other disadvantages are instability especially during uncertain economic times.
Is the daytime sky blue because of the greenhouse effect?
i don't think so, the blue color of the sky is because of the dispersion of light, as when the light reaches the sky it has minimum wavelength when reflected so it appears blue, as the blue color has minimum wavelength
What is the minimum mass a triple beam balance measure?
0.01g
Which thermometer is used to measure atmospheric temperature?
Maximum minimum thermometer
Can a box plot have no whiskers?
Yes. For example, if at least a quarter of the observations were all equal to the minimum then the left whisker would collapse into the left side of the box. Similarly, if a quarter of the observations were equal to the maximum, the right whisker would not appear.
How to measure Maximum and minimum temperature at a place?
its a simple answer........................................................................... thermometer se. hahahahahahahahahah
