i need a response to my classmates attached post Diane FelixOffline Diane Felix How Do We Interpret Descriptive Statistics and Visual Distributions? by Diane Felix Jul 17 Actions After generating descriptive statistics and a histogram for the Project Grade variable, I analyzed the data's distribution using visual cues and numerical measures. Histogram Interpretation The histogram visually displays an uneven shape, with a spike in clusters in the 71-76 range, and a notable dip with clusters in the 76-81 range. The visual distribution lacks the smooth curve of a classic bell shape. Based on the height and spread of the bars, the distribution appears flat and somewhat irregular, though not dramatically skewed. Comparing Descriptive Statistics for Project Grade According to the descriptive statistics: Mean = 77.43 Median = 75.74 Skewness = 0.0401 (very close to zero) Kurtosis = -1.362 Standard Deviation = 13.17 The values support what we can visually see on the histogram. The mean and median are close, suggesting the data is relatively symmetrical and not heavily skewed. A skewness near zero indicates the data is not heavily skewed in either direction. The negative kurtosis value confirms that the distribution is flatter and broader than normal. Does It Resemble a Normal Distribution? The distribution for the project grade dataset is not a normal distribution; however, it doesn't appear extremely skewed. Instead, it shows a flattened curve and multiple peaks, suggesting
