Exploring Dot Plots and Histograms

What does each dot in a dot plot represent?

• A category of data

• A range of values

• An individual data point

• The median of the dataset

How do you find the median in a dot plot?

• By counting the dots and dividing by two

• By crossing off dots from each side until you reach the middle

• By finding the dot with the highest frequency

• By calculating the average of all the data points

What does the height of a bar in a histogram represent?

• The range of data

• The median of the data

• The frequency of data within an interval

• The total number of data points

What is a 'bin' in the context of histograms?

• A type of histogram

• The space between bars

• The height of each bar

• The range of data each bar covers

In histograms, what does continuity of data imply?

• Each bar represents a single data point

• There are no gaps between the bars

• Data points are spread out evenly

• All data points are equal

What does it mean if a histogram is described as 'bimodal'?

• It represents two different datasets

• It has a single peak

• It is perfectly symmetrical

• It has two peaks

What is the relationship between mean and median in a symmetrical histogram?

• Mean is greater than median

• There is no relationship

• Mean is less than median

• Mean and median are approximately equal

In a skewed histogram, where is the mean in relation to the median?

• The mean is always higher than the median

• The mean is always lower than the median

• The mean and median are the same

• The mean is to the left or right of the median, depending on the skew direction

How can you visually determine if a histogram is skewed to the left?

• The tail of the histogram extends to the right

• All bars are of equal height

• The highest bar is on the left side

• The tail of the histogram extends to the left

What does standard deviation measure in a dataset?

• The average value of the data

• The median value of the data

• How spread out the data points are from the mean

• The difference between the highest and lowest values
