1 - 8, unless there is a logical reason for another interval.
All five points are reasonable.
illustrate how you can express the age of group of persons as {1}nominal,{2}ordinal data,{3} interval data,{4}ratio data
Interval Data: Temperature, Dates (data that has has an arbitrary zero) Ratio Data: Height, Weight, Age, Length (data that has an absolute zero) Nominal Data: Male, Female, Race, Political Party (categorical data that cannot be ranked) Ordinal Data: Degree of Satisfaction at Restaurant (data that can be ranked)
What is the interval notation of -1<5x+1<4
1 to 8, surely!

if data is in the form of frequency distribution then the modal range is the interval containing the highest frequency of observations

n=1+3.3logN n is equal to the class interval N is equal to the number of raw data given you must compute first the expression logN then multiply it by 3.3 then add 1
Gap: ina data display, a large space between data points.Ex. 3,4,5, Gap 20,22Cluster: in a data display, a cluster is several data points lie in a small interval. Ex. 7,8,9,0,2345678Outliers: A number ina set of data that is much larger or smaller than most of the other numbers in the set.Ex. 1, ( outlier ) 52, 55, 57,59, 129 (outlier)
What is the interval notation of -1<5x+1<4
If none of the numbers in a set of data are repeated you have two options: Options 1: leave the data set as it is and call every value a mode. One instance when the mode is hardly a useful measure. Option 2: Group the data and find the class interval with the highest frequency density. This would be the modal interval. Note, though, that the class intervals that you choose will influence the result.
the smallest is 1/2 a centimeter and the largest is 1/2 an inch
A 1-dimensional interval (a, b) is continuous if for any k in (0, 1) the point a + k*(b-a) = a*(1-k) + k*b is also in the interval. This is equivalent to the statement that every point on the line joining a and b is in the interval. The above can be extended to more dimensions analogously.
