The independent variable in ANOVA must be categorical (either nominal or ordinal). The dependent variable must be scale (either interval or ratio). However, it is possible to recode scale variables to categorical and vice versa in order to perform ANOVA. While this is a common practice in many Social Sciences, it is controversial. I have also seen studies where ordinal data is treated as scale in ANOVA. Personally, I do not endorse either practice as they are tailoring the data to fit the test instead of the proper method of selecting a test that fits the data.
The null hypothesis for a 1-way ANOVA is that the means of each subset of data are the same.

No. Variance and standard deviation are dependent on, but calculated irrespective of the data. You do, of course, have to have some variation, otherwise, the variance and standard deviation will be zero.
A nominal number names something-a telephone number, a player on a team. Nominal numbers do not show quantity or rank. They are used only to identify something.Here are some examples using nominal numbers:jersey number 4zip code 02116
Nominal values are the values that a component is specified to be. For example, the nominal value of a 10K resistor is 10K. Its actual value may vary, though, based on its tolerance.
ANOVA (Analysis of Variance) is used for interval and ratio level data because it relies on the assumption that the data is continuous and normally distributed, allowing for meaningful calculations of means and variances. Nominal and ordinal data do not meet these criteria; nominal data consists of categorical variables without a numerical relationship, while ordinal data has a ranked order but does not provide equal intervals between ranks. Consequently, ANOVA is not appropriate for these data types as it cannot accurately assess differences in means or variances.
The null hypothesis for a 1-way ANOVA is that the means of each subset of data are the same.
ANOVA test null hypothesis is the means among two or more data sets are equal.
nominal
If you are bothering to measure it, it probably is not nominal data in your study.
Yes, marital status is nominal data.
No, it is not suitable for nominal data.
Yes, marital status is nominal data.
Nominal
They are part of nominal data if the study is about different kinds of methods for displaying statistical data.
The abbreviation ANOVA stands for analysis of variance. It is used for carrying out comparative analysis of the statistical methods to determine if there is any relationship between data points.
It depends on the type of data you are analyzing. For research, common methods for analyzing data are t-tests, ANOVA, MANOVA, and chi-square.
