Which of the following types of data is suitable for a t-test?*NominalOrdinalIntervalCategoricalNone of the above

The t-test is suitable for Interval data. Here's why:

1. Nominal data: This type of data is categorical and does not have a specific order or priority. It's not suitable for a t-test because a t-test requires numerical data.

2. Ordinal data: This type of data is also categorical, but it has a specific order. However, it's still not suitable for a t-test because the differences between the categories are not equal.

3. Interval data: This type of data is numerical and the differences between the values are equal. This makes it suitable for a t-test because a t-test compares the means of two groups and determines if they are significantly different from each other.

4. Categorical data: This is similar to nominal data where the data is grouped into categories. It's not suitable for a t-test because a t-test requires numerical data.

So, the correct answer is Interval data.
