How many types are there of frequency distribution?
Introduction:Frequency distribution is used to compress and summarize the whole data by grouping the data into classes and records the data points that fall in each class. The frequency distribution is considered as the base for descriptive statistics and they are also used to define the ordinal, nominal and the interval data. Frequency distribution is the comfortable way of grouping and organizing the data.Example of Frequency Distribution:Consider the frequency table for the students in a class where the data has been grouped according to the height of the students. Range of height Total number of student's cumulative frequency3.0 - 4.5 feet 15 154.5 - 5.0 feet 20 355.0 - 6.5 feet 25 506.5 - 7.0 feet 30 80In the case of nominal data the use of the contingency table is required. The frequency distributions are used to present the data graphically.Types of Frequency Distributions:There are three types of frequency distributions. Cumulative frequency distribution,Grouped frequency distribution,Cumulative Grouped frequency distribution.Cumulative frequency distribution (type 1):The cumulative frequency can be found from the frequency distribution by adding the cumulative frequency column. The highest cumulative frequency should be equal to the total number of frequenciesTemperature Frequency Cumulative frequency47 3 2246 3 1945 4 1544 3 1243 3 9Grouped frequency distribution (type 2):The grouped frequency distribution can be formed by grouping the values together into the class intervals.

What are the nominal variables in economics?
Variables measured in monetary units
What is an equivalent rate?
Equivalent RatesThe Equivalent Rates calculation is used to find the nominal annual interest rate compounded n times a year equivalent to a given nominal rate compounded m times per year.Two nominal rates with different compounding frequencies are equivalent if they yield the same amount of interest per year (and hence, at the end of any period of time).Input• nominal annual rate for the given rate• compounding frequency for the given rate• compounding frequency for the equivalent rateResults• equivalent nominal annual rate• equivalent periodic rateExample•A bank offers 14.75 % compounded annually.What would be the equivalent rate compounded monthly?InputGiven nominal annual rate:14.75 %Compounding frequency for given rate:annuallyCompounding frequency for equivalent rate:monthlyResultEquivalent nominal annual rate:13.8377 %Answer: 13.8377%.
What type of variable is gender?
Nominal (categorical), and Dependent (it is measured and accounted for, but a researcher cannot manipulate gender).
What test to use for non-normal distribution with data that's not nominal?
It depends on what you want to test. Goodnesss of fit or some null hypothesis?
When data is collected using a qualitative nominal variable male or female what is true about a frequency distribution that summarizes the data?
class midpoints can be computed
