descriptive

Descriptive Statistics: -The mean (average) age of the survey respondents was 35 years. -The median income for the sample group was $50,000 per year. -The standard deviation of test scores was 10 points, indicating a relatively wide spread of results. -The range of temperatures recorded over a week ranged from a low of 40°F to a high of 90°F. -The mode of transportation most commonly used by commuters was the subway. -The interquartile range (IQR) for the dataset suggests that the middle 50% of values are fairly tightly clustered. -The data set for product sales showed a positively skewed distribution. -90% of the survey participants reported being satisfied with the new company policy. -The coefficient of variation for a dataset of investment returns indicated a high level of risk. -The distribution of student grades in the class appeared to be normally distributed with a slight skew towards higher grades.Inferential Statistics: -A t-test revealed that there was a statistically significant difference in the mean test scores between the two groups. -A chi-square test indicated a significant association between smoking and the development of lung cancer. -A regression analysis suggested a strong positive relationship between advertising spending and sales revenue. -An analysis of variance (ANOVA) showed that there were significant differences in the performance of different teaching methods. -With a confidence level of 95%, we can estimate that the population mean income falls within a certain range. -A Pearson correlation coefficient of 0.80 suggests a strong positive linear relationship between two variables. -A hypothesis test found that there was not enough evidence to support the claim of a new drug's effectiveness. -Using a Monte Carlo simulation, we estimated the probability of a stock portfolio losing value in a given year. -A logistic regression model was used to predict the likelihood of customer churn based on several independent variables. -A Bayesian analysis was conducted to update the probability of a rare event occurring, given new evidence and prior beliefs.
