In rqti: Create Tests According to QTI 2.1 Standard

# Generate normal distribution values
set.seed(123)
n <- 100  # Number of values
mu <- 0   # Mean of the distribution
sigma <- 1  # Standard deviation of the distribution
values <- rnorm(n, mean = mu, sd = sigma)

# Present the values
# summary(values)

# Generate and display the histogram plot
library(ggplot2)
histogram <- ggplot(data.frame(values), aes(x = values)) +
    geom_histogram(fill = "steelblue", color = "white") +
    labs(title = "Histogram of Normal Distribution Values", x = "Values", y = "Frequency")
ggsave("ND.png", plot = histogram, width = 3, height = 3, dpi = 300)

question

Which type of histogram is shown on the picture?

• Bernoulli Distribution
• Binomial Distribution
• Poisson Distribution

feedback

The correct answer is Histogram of Normal Distribution Values. According to the definition, this distribution has the follow view:

{width=300px height=300px}
