Which kind of graph will not let you calculate the range? Is it a bar graph, line graph, circle graph, or a pictograph?
To determine which kind of graph does not let you calculate the range, let's first understand what the range represents.
The range is a measure of dispersion or the difference between the highest and lowest values in a dataset. It gives us an understanding of the spread of data. To calculate the range, we subtract the lowest value from the highest value.
Now, let's analyze each type of graph you mentioned to see if we can calculate the range:
1. Bar graph: A bar graph represents data using rectangular bars, where the length of each bar corresponds to the quantity it represents. Bar graphs can include both categorical and numerical data. However, if the bars only represent categories or groups, such as comparing favorite colors or types of pets, the concept of range is not applicable here.
2. Line graph: A line graph shows the relationship between two variables plotted on the x and y-axes, usually with points connected by lines. While line graphs are commonly used to display trends and changes over time, they can also represent ranges, especially when multiple lines are present. In this case, the highest and lowest values can be identified, allowing for the calculation of the range.
3. Circle graph (also known as a pie chart): A circle graph represents data as portions of a circle, where each portion (or slice) corresponds to a specific category or value. Circle graphs are useful for displaying proportions or percentages of a whole, but they don't directly provide the necessary information to calculate the range. They focus more on the distribution of data rather than the range itself.
4. Pictograph: A pictograph uses pictures or symbols to represent data values. Similar to bar graphs, if the pictures or symbols only represent categories or groups, determining the range would not be applicable. However, if the pictograph represents quantitative data where pictures/symbols represent a fixed quantity, it may be possible to calculate the range.
Based on this analysis, the kind of graph that does not typically allow for the calculation of the range is the circle graph (pie chart).
