Complete the table below by identifying the appropriate data-gathering instruments, data processing techniques, non-prose materials, and statistical tests for the given scenario. Explain the reasons behind your choice. Tricia wants to determine if her organization’s new counseling technique decreases the anxiety level of single mothers in their community. Specifically, she wants to address the following research questions: Is there a significant decrease in the anxiety level of single mothers subjected to the counseling technique? Is there a difference in the anxiety level of the control and experimental groups after the intervention? How do the single mothers respond to the counseling technique? To do this, she will use two intact groups: one control group and one experimental group. There will be 98 participants in the study. Fifty will be assigned to the experimental group who will be subjected to the new counseling technique. The rest will be assigned to the control group who will be subjected to the standard counseling technique.

Addition Rule of Probability
It simply refers to the likelihood of an event taking place whenever the occurrence of an event is uncertain. The probability of a single event can be calculated by dividing the number of successful trials of that event by the total number of trials.
Expected Value
When a large number of trials are performed for any random variable ‘X’, the predicted result is most likely the mean of all the outcomes for the random variable and it is known as expected value also known as expectation. The expected value, also known as the expectation, is denoted by: E(X).
Probability Distributions
Understanding probability is necessary to know the probability distributions. In statistics, probability is how the uncertainty of an event is measured. This event can be anything. The most common examples include tossing a coin, rolling a die, or choosing a card. Each of these events has multiple possibilities. Every such possibility is measured with the help of probability. To be more precise, the probability is used for calculating the occurrence of events that may or may not happen. Probability does not give sure results. Unless the probability of any event is 1, the different outcomes may or may not happen in real life, regardless of how less or how more their probability is.
Basic Probability
The simple definition of probability it is a chance of the occurrence of an event. It is defined in numerical form and the probability value is between 0 to 1. The probability value 0 indicates that there is no chance of that event occurring and the probability value 1 indicates that the event will occur. Sum of the probability value must be 1. The probability value is never a negative number. If it happens, then recheck the calculation.
