Qualtrics XM for Strategy & Research Expert Certification Journey (L2) with correct answers 100% Numerical Data - Correct Answer Any data that is only numbers. Examples include height, weight, age, and number of children Categorical Data - Correct Answer Non-numeric data with no specific order. Examples include favorite color, country of residence, and brand of jeans. P-value - Correct Answer statistical test, the probability of getting the same or more extreme value if our data actually had no trend (i.e, was random). Generally, P-values less than .05 (5%) are considered significant. Population - Correct Answer The range of all possible values that could be sampled from. Confidence Interval - Correct Answer A range of values with a defined probability of containing the true value of a variable. Generally, a 95% confidence interval is used T-Test - Correct Answer A significance test that compares a numeric value between two groups. ANOVA - Correct Answer A significance test that compares a numeric value for three or more groups. Chi-Squared - Correct Answer A significance test that compares two categorical variables Regression - Correct Answer A formula that calculates a predicted value for one numeric variable based on its relationships with other variables. Time series - Correct Answer Similar to a regression, time series predicts the future value of a variable based on its past values and trends. Logistic Regression - Correct Answer type of regression that calculates the odds of someone belonging to two or more groups.

Any numeric variable in your dataset What is the highest and lowest confidence level that you can apply - Correct Answer The lowest possible value is 60% and the highest possible value is 99.% What are workspaces - Correct Answer Workspaces are like tabs in a spreadsheet. There is no right or wrong number of workspaces and no limit to the number of workspaces you can create.
