Name a type of test you can't study for?
A type of test you can't study for is an IQ test, as it measures innate cognitive abilities rather than learned knowledge. These tests assess skills such as problem-solving, logical reasoning, and pattern recognition, which are typically stable traits rather than acquired skills. While some familiarity with the test format may help, the core abilities measured are not subject to study or preparation.
If group a has a higher mean than group b the research hypothesis is directional or non directional?
Whether your alternate hypothesis is directional (one-sided) or non-directional (two-sided) is largely up to you but must be determined before you conduct your experiment, not after. It's not defined by the outcome.
What is the area along the bottom of a chart that identifies the categories of data?
If you mean the box that lists the meanings and values of all the various colors, symbols, letters, etc. found on the entirety of the chart, it's called the legend. If you mean, specifically, the line that runs from left to right across the chart, a line used in many but not all types of charts, it's called the abscissa. That term is rarely used, though. It is most often called the x-axis or the category axis.
Internal validity is higher when you stop confounding variables interfering with the experiment (things that effect the results). Internal validity occurs when a researcher controls all confounding variables and the only variable influencing the results of a study is the one being manipulated by the researcher. This means that the variable the researcher intended to study is indeed the one affecting the results and not something else.

- estimates for the mean or standard deviation are incorrect, or
