Question

1. what are three different ways to analyze data?
2. explain how to calculate the mean of data.
3. what are two benefits of using charts and graphs during a presentation?
4. what is the first step to determining the best way to convey data visually?

Explanation:

Step1: Analyze data

Three ways: descriptive (summarize), inferential (draw conclusions), predictive (forecast).

Step2: Calculate mean

Sum all data values, divide by number of values. Formula: $\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$.

Step3: Benefits of charts/graphs

Simplify complex data, highlight trends/patterns.

Step4: First step for visual data

Identify the data type (qualitative/quantitative).

Answer:

1. Descriptive, inferential, predictive analysis.
2. Sum all data values and divide by the number of values ($\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$).
3. Simplify complex data, highlight trends/patterns.
4. Identify the data type (qualitative/quantitative).
